Final answer:
Muscles are indeed stronger during eccentric contractions than concentric contractions, with the former occurring when a muscle lengthens under force and the latter when it shortens.
Explanation:
The statement 'Muscles are stronger eccentrically than concentrically' is true. An eccentric contraction occurs when the muscle lengthens while producing force, often acting as a braking force to protect joints. The muscle is resisting a force greater than the force it is producing, and this type of contraction is more powerful than when the muscle shortens, as in a concentric contraction.
For example, when you lower a hand weight, your biceps perform an eccentric contraction. During eccentric contractions, muscles can absorb and control more force than during concentric contractions, where the muscles shorten to move a load, like lifting the weight upwards. This difference in strength during these types of contractions is utilized in various exercises and movements that require control, balance, and resistance to opposing forces. Hence, the correct answer is a. true.
A substance X is secreted by one cell, it travels a short distance through interstitial fluid, and produces an effect in a cell immediately adjacent to the original secreting cell. All of the following terms might fit this substance except:
A. Prostaglandin
B. Neurotransmitter
C. Pheromone
D. Growth factor
E. Nitric acid
Answer:
The answer to the question: All of the following terms might fit this substance except:____, would be, C: Pheromone.
Explanation:
In general terms, the body has a lot of chemical substances that work as communication ways between cells of the same tissues, tissue groups, organs and organ systems. Most of these will be produced by a specific cell and will travel to other cells where they will produce an effect, all within the same body. However, from the list given here there is one that is a chemical substance, produced and secreted by the cells of the body, but whose purpose is rather to produce an effect on other bodies around it, and not over its own. This substance is known as a pheromone and its function is to generate a reaction of attraction from other members of the same species, in this case, humans.
The metacarpals articulate with the
a. proximal carpals
b. phalanges
c. ulna
d. radius
Answer:
b. Phalanges
Explanation:
The metacarpals are the five bones that form and support the hand and articulate distally with the proximal phalanges, the bones that form the fingers, and proximally with the distal carpals. The carpus is composed of eight bones that connect the hand with the forearm, those bones are divided into distal and proximal, distal means far from the midline and proximal means near to it. Therefore, the distal part of the carpus is the one that articulates with the metacarpals.
The ulna and the radius are the bones that form the forearm and articulate with the proximal carpals.
Where is the esophagus positioned relative to the trachea?
Answer:
Explanation:
The esophagus is a structure which is located in between the trachea and left atrium of the heart. It actually lies behind the trachea and situated on the left side of the atrium of the heart. The esophagus is a tube that connects the throat with the stomach. It is 8 inches long, and it is covered by by moist pink tissue that is called mucosa. The esophagus is situated behind the windpipe (trachea) and heart, and typically can be seen in front of the spine.
The esophagus is a muscular tube that connects the pharynx to the stomach and is positioned posterior to the trachea.
Explanation:The esophagus is a muscular tube that plays a crucial role in the digestive process by connecting the pharynx to the stomach. It is located posterior to the trachea, running a relatively straight course through the mediastinum of the thorax. When we swallow, the esophagus extends and allows food to pass through, whereas when not in use, it remains in a collapsed state. To reach the stomach, the esophagus must pass through the diaphragm via the esophageal hiatus.
The gubernaculum is found in both the male and female embryo. What does it form in the baby and adult females?
Answer:
The answer to the question: The gubernaculum is found in both the male and female embryo. What does it form in the baby and adult females, would be: It forms the 2 rounds ligaments of the uterus, one to anchor each side of this pear-shaped reproductive organ and its companions in the reproductive system.
Explanation:
During embryologic differentiation, both the male and female embryos have in their bodies the gubernaculum. The gubernaculum is a mesenchyal tissue of undifferentiated cells that can be found attached to both the ovarian tissues in female fetuses, and the testicular tissue of male ones. In the female fetus, this gubernaculum starts its differentiation during the urogenital formation stages, and it forms a sort of band of connective tissue that initiates from the ovaries and then starts extending during developing towards the cornu of the uterus, where it attaches and then continue extending towards the labia majora. These two ligaments, one from each ovary, will attach either side of the uterus and will become its binding and attachment to the pelvic area, and also for all other reproductive organs.
What is the expected response of systolic blood pressure (SBP) as workloads increase during a graded exercise test?
a. The SBP should remain the same.
b. The SBP should increase.
c. The SBP should decrease.
Answer:
The answer to the question: What is the expected response of the systolic blood pressure (SBP) as workloads increase during a graded exercise test, would be, B: The SBP should increase.
Explanation:
Systolic blood pressure is basically the force that the blood exerts over the vessel walls, as it travels through them, once it is ejected from the heart. The blood volume, the amount that is pumped by the heart, and also the resistance placed by the vessels themselves against the blood, all contribute to blood pressure. The name of systolic, or diastolic, comes from the two cycles of the heart, systole, when most of the blood is actively ejected from the heart, and the other when the heart begins to relax and prepare for a new pump. During exercise, especially if it is moderate and increasing, what is expected is for SBP to rise, until 2 to 3 minutes into it, the rising levels off, and becomes constant. But intially, it will rise.
The expected response of systolic blood pressure (SBP) as workloads increase during a graded exercise test is b. The SBP should increase.
During exercise, particularly in a graded exercise test, the heart works harder to pump blood throughout the body to meet the increased oxygen demand. This leads to an increase in systolic blood pressure (SBP) because the heart pumps more forcefully and more frequently. An increase in SBP during exercise is considered a normal physiological response. For example, a typical SBP might rise from a resting level of around 120 mmHg to over 200 mmHg during intense physical activity. This increase helps deliver more oxygen and nutrients to the muscles and tissues being used.It is important to understand both systolic and diastolic pressures for comprehending blood pressure dynamics:
Systolic Blood Pressure (SBP) is the pressure exerted on blood vessels when the heart is contracting to pump blood. It is the higher number in a blood pressure reading, and a healthy range is generally from 90 to 120 mm Hg.Diastolic Blood Pressure (DBP) represents the pressure in the arteries when the heart is at rest between beats, with the ideal range between 60 and 80 mm Hg.A graded exercise test typically involves progressively increasing levels of exertion. As workloads rise, the cardiovascular system responds by elevating SBP to ensure that sufficient blood and oxygen are being supplied to the active muscles. This is a natural and expected outcome of increased physical activity.
In terms of what is happening within a resting skeletal muscle cell why are myosins not be able to attach to the thin myofilament?
Answer:
The answer to the question: In terms of what is happening within a resting skeletal muscle cell, why are myosins not able to attach to the thin myofilaments, would be: because there is no presence of calcium ions to enable to fusion of the two.
Explanation:
When muscle cells, and a muscle in general, wish to perform one of their functions, which is movement, there are some factors that need to be present in order for this to work. One vital factor is the presence of calcium ions, because it is calcium which will enable the proper formation of the myosin-actin cross bridges for movement. Basically, calcium allows the removal of the protection on these filaments and makes them active, so that they will immediately seek the formation of the cross-bridges. To stop this from happening, calcium is re-absorbed by the sarcoendoplasmic reticulum.
The function of the vibrissae in the vestibule is to:
a. provide a large, mucus-covered surface area over which air must pass before reaching the pharynx.
b. provide an initial "filter" to screen particulate matter from air that is entering the system.
c. produce copious quantities of mucus.
d. serve as resonating chambers for speech.
Answer:
A correct answer is an option - B. provides an initial "filter" to screen particulate matter from the air that is entering the system.
Explanation:
The vestibule is the most anterior region of the nasal cavity lined with epithelium skin and surrounded by the cartilage with the small hair present in it. These nasal hairs are known as vibrissae.
Vibrissae are present on the nasal cavity opening and play the role of filters as they trap dust and particle from the air inhaled by the respiratory system.
Thus, the correct answer is option B.
In people who engage in regular vigorous exercise, RMR may account for a larger proportion of daily caloric need.
a. True
b. False
Answer: False
Explanation:
RMR is Resting metabolic rate is the rate at which the body burns the energy while in rest. This can be calculated by how much calories are burn while in rest in vital processes such as breathing and circulation. It is irrespective of the exercise and physical strain taken by the person in awake state. Thus the RMR will only account for small proportion of the caloric needs.
The three structures found at the renal hilum are the __________, __________ and renal artery.
Answer:
The answer is: renal ureter, renal vein, and renal artery.
Explanation:
The renal hilum is a depression or fissure which transmits the blood vessels from the kidney.
The renal hilum consists of the following three structures: renal artery, renal vein, and the renal ureter.
The renal artery enters, and the renal vein and renal ureters exits the kidney from the anterior to the posterior.
The renal hilum is an entry and exit point at the kidney for the renal vein, ureter, and renal artery. These structures facilitate the transport of blood and urine to and from the kidneys.
The three structures found at the renal hilum are the renal vein, ureter, and renal artery. The renal hilum serves as the entrance and exit for structures servicing the kidneys. The arrangement of these structures is in an anterior-to-posterior manner, with the renal pelvis emerging from here, which is formed from the major and minor calyces. The renal vein returns cleansed blood to the inferior vena cava while the renal artery brings blood from the descending aorta to be filtered.

c. Amantadine
d. Pergolide
Answer:
The correct answer is D.
Explanation:
Carbidopa is a drug that inhibits peripheral metabolism of levodopa. For Parkinson disease treatment carbidopa is added to levodopa. This allows a greater proportion of levodopa to cross the blood brain barrier and have a therapeutic effect in central nervous system.
This substance, a waste product from muscle metabolism, is one indicator of kidney function______________.
Answer:
creatinine
Explanation:
The creatinine it's a protein compound that is the result of the metabolism of the muscles, this protein is produced constantly, depending of the muscle mass of each individual, which should be excreted in urine, therefore an elevated creatinine in blood sugests kidney injury, because it means creatinine is not being filtrated correctly by the kidneys
The relationship between the maxillary and mandibular teeth, when the teeth are touching and the mouth is gently closed, is known as what?
a. occlusion
b. abutment
c. facial alignment
d. sulcus measurement
Answer:
The correct option is: a. occlusion
Explanation:
The maxilla is the bone that forms the upper jaw, formed by the joining of the two maxillary bones. It is the fixed part of the jaw that holds the upper teeth.
The mandible, also known as the jawbone, is the largest bone of the human face that forms the lower jaw. It is the movable part of the jaw that holds the lower teeth.
During chewing or resting, when the teeth are gently closed or touching, the relationship between the mandibular or the lower teeth and the maxillary or the upper teeth is known as the occulation.
Answer:
a. occlusion
Explanation:
Occlusion is basically the branch of dentistry that studies the bite relationships between the upper and lower dental arch. However, the definition is complete only when considering the dynamic, morphological and functional relationship between all components of the masticatory organ, of which the teeth, the supporting structures of the teeth, the neuromuscular system, the temporomandibular joints and the craniofacial skeleton constitute it. In other words, we can say that the relationship between the jaw and jaw teeth, when the teeth are touching and the mouth is gently closed, is known as occlusion.
The mandibular movements are coordinated and directly linked to the neurological system, which explains the mandibular dislocation to one side and change of the body axis, due to occlusal interference and premature contacts, for example.
These conditions can cause tension, fatigue, hyperactivity, spasms, and pain in the chewing muscles and head and neck postures until the occlusal change is corrected.

Answer:
Thyroid cartilage
Adam's apple
Explanation:
Adam's apple is a cartilaginous structure that protrudes from the anterior angle of the thyroid cartilage located at the level of the larinx, Adam's apple is more prominent in men due to the hormonal influence of testosterone, so it is related in the developing of the deeper voice tone of the males.
The most inferior cartilage of the larynx is the _________ and serves as the landmark for tracheotomies.
Answer:
The best answer to the question: The most inferior cartilage of the larynx is the:____ and serves as the landmark for tracheotomies, would be: the cricoid cartilage and the place where even unskilled medical respondents can perform cricothyrotomy, in case of acute respiratory obstruction is known as the cricothyroid membrane which connects the upper thyroid cartilage and the lower cricoid cartilage.
Explanation:
In the structure of the larynx, there are several cartilaginous structures, and bony structures, that provide both support and protection to the tube that connects the upper airways with the lower airways and the lungs. These cartilages ensure that these functions are provided and that air and foodstuffs, including water, reach the proper places. On the larynx, going down towards the lungs, we have three single cartilaginous structures and three paired ones, before it turns into the trachea. The two lowest ones are the thyroid and the cricoid. These two are also joined by the cricothyroid membrane. The cricoid is the lowest, or most inferior of the cartilages and it is also the place where health professionals seek the mark to perform what is known as cricothyrotomy, or, tracheostomy.

b)Removal of a kidney stone by passing a small tube through the urethra and bladder.
c)Using soundwaves to break up stones into smaller pieces that can then pass naturally.
d)Removal of the parathyroid glands which are allowing calcium buildup in the kidneys.
Answer: c)Using soundwaves to break up stones into smaller pieces that can then pass naturally.
Explanation:
The extracorporeal shockwave lithotripsy is a method or technique which is used to break the stones which may be present in the kidney or ureter. The high energy shock waves can also be in the form of soundwaves. This technology breaks the stones without surgery and into small pieces like that of sand grains.
Are the cartilage rings visible in the trachea and bronchi?
Answer:
The best answer to the question: Are the cartilage rings visible in the trachea and bronchi, would be: yes.
Explanation:
Both the larynx, trachea and bronchi, with the exception of the tertiary bronchi that already branch into the lungs themselves, have visible, white-like, cartilaginous rings that give them support, and protect them from impact. These rings, from the trachea, to the bronchi, can be seen as successive ring-like downwards structures that surround the softer muscular tubes. They are made of cartilage because these structures need flexibility and easiness of expansion. But they can be seen.
a patient who exhibits a weak pulse, shallow or absent
breathing, delirium or coma, and blue lips is most likely suffering
from which type of drug overdose?
Answer:
Opioid
Explanation:
An opioid is any psychoactive chemical compound that produces pharmacological effects similar to opium or its substances, although not chemically related. Opioids act on opioid receptors, with effects similar to morphine, for example. It is used as an analgesic because it conveys a strong sensation of pain relief, however the constant use of this compound can lead to addiction and even withdrawal symptoms when someone addicted does not have access to it. Patients with opioid withdrawal usually have weak pulse, shallow or absent breathing, delirium or coma, and blue lips .
Final answer:
A patient with a weak pulse, shallow breathing, and blue lips is likely experiencing an opioid overdose, and naloxone is used as an antidote.
Explanation:
A patient exhibiting symptoms such as a weak pulse, shallow or absent breathing, delirium or coma, and blue lips is likely suffering from an opioid overdose. Opioids are known depressants which can slow or stop a person's breathing, often leading to an overdose death.
To combat such an overdose, the opioid-overdose antidote naloxone is used to help the person awaken and breathe until emergency medical treatment can be provided. It's important to note, however, that similar symptoms can be caused by other conditions or overdoses of different substances, such as barbiturates or in cases of severe metabolic acidosis.
A 29-year-old man who lives at the sea level drives up to a high altitude (17,000 feet) for over 3 hours. Which of the following statements best describe his condition after the elevation climb?
A. Increased arterial PO2
B. Decreased arterial PCO2
C. Decreased arterial pH
D. Decreased respiratory rate
Answer:
D. Decreased arterial PCO2
Explanation:
pO2 decreases exponentially with altitude, this leads to an increase in the respiratory rate in an attempt to gain equilibrium, this leads to a decreasing arterial pCO2, this will displace the equilibrium of gases exchanged resulting in a loss of H+ and leading to respiratory alkalosis, an increasing on arterial's pH.

Enzyme-linked Immunosorbent Assays are assays in which both ________ and ____________ reactions are utilized.
Answer:
Enzyme-linked Immunosorbent Assays are assays in which both antigen and antibody reactions are utilized. It is an enzyme immunoassay in which a specific antigen with unknown amount is immobilized on the ELISA plate and a specific enzyme is added which is conjugated with an enzyme.
This enzyme is responsible for reacting with the substrate and on the reaction substrate gives a specific color. So higher the amount of antibody bounded with antigen higher will be the production of color.
In indirect ELISA two antibodies are used and the second antibody is conjugated with an enzyme and binds specifically with primary antibody. Primary antibody is already bonded with antigen. In indirect ELISA nonspecific binding is restricted so detection is more accurate.
Enzyme-linked Immunosorbent Assays (ELISAs) utilize both immunological and enzymatic reactions to detect the presence of specific antigens, with variations such as direct and indirect ELISA offering different sensitivities and signal amplification.
Explanation:Enzyme-linked Immunosorbent Assays (ELISAs) are assays in which both immunological and enzymatic reactions are utilized. In a direct ELISA, an enzyme-conjugated antibody binds to its specific antigen immobilized on a microtiter plate. After the addition of a colorless substrate for the enzyme, a colored product is formed if the target antigen is present. The intensity of the color is usually proportional to the amount of antigen. In the indirect ELISA, the process involves a primary antibody binding to the antigen and a secondary enzyme-conjugated antibody recognizing the primary antibody, allowing for signal amplification.
An XY individual with androgen insensitivity syndrome (AIS) will develop
a) testes, external female genitalia, neither intermal genitalia
b) testes, external female genitalia, female internal genitalia
c) testes, external female genitalia, male internal genitalia
d) ovaries, external male genitalia. neither internal genitalia
e) ovaries, external male genitalia, male internal genitalia
Answer:
The correct answer is A.
Explanation:
Androgen insensivity syndrome (AIS) is a genetic autosomal recessive disease linked to X chromosome.
During development, an 46XY embryo with AIS cannot process the androgens produced by the testes, but they do respond to other hormones, therefore the testes form and function during embryonic development.
Testes produce Müllerian inhibiting hormone, which stops the development of uterus, fallopian tubes and cervix.
But the Wolffian ducts aren’t able to respond to androgens secreted by the testes, so as a result, they don’t turn into prostate gland, spermatic ducts, ejaculatory ducts or seminal vesicles.
External genitalia develop as a normal 46XX female fetus, because they don’t respond to testosterone and dihydrotestosterone (androgens )
An XY individual with androgen insensitivity syndrome (AIS) will develop a) testes, external female genitalia, neither internal genitalia
Androgen Insensitivity Syndrome (AIS) occurs in individuals with an XY chromosome pattern, where their bodies cannot properly respond to male sex hormones (androgens).As a result, they develop testes, which are usually undescended or located in the inguinal canal or abdomen.Despite having testes, the external genitalia develop as female due to the lack of androgen effect, leading to the appearance of a typical female external phenotype.The internal genitalia, including the uterus and fallopian tubes, do not develop because the testes produce anti-Müllerian hormone (AMH), which inhibits the formation of these structures.Male internal genitalia do not develop properly either due to androgen insensitivity, resulting in the absence of both male and female internal genitalia structures.The AV node is located
a. in the bottom of the atrium just above the ventricles

These cells provide for the sense of smell.
a) Olfactory hair cells
b) Gustatory cells
c)Basal stem cells
Answer:
The answer to the question: These cells provide for the sense of smell:___, would be, A: Olfactory hair cells.
Explanation:
The sense of smell might be one of the most primitive, but also one of the most amazing senses of the human system. This sense initiates with the introduction of smells, in the form of chemical molecules dissolved in air, that once they come into contact with the mucus in the nostrils dissolve and reach a group of cells, on the olfactory epithelium known as the olfactory receptor neurons. These cells capture the chemicals and send neural signals towards the olfactory bulbs, where sensory neurons relay the messages towards the brain centers. In the brain, several steps take place in order to gain sense, comprehension and assimilation of the smell that has been captured.
What is tennis elbow?
Explanation:
Tennis elbow -
It is painful condition which occurs when the tendons in the elbow gets overloaded , which occurs due to the repetitive motions of the arm and wrist.
Tennis elbow is very common , and commonly athletes face it .
The pain can even spread to the forearm and wrist .
In extreme case can can even lead to surgery .
Tennis elbow is a form of tendinitis resulting from overuse of the elbow joint, often caused by playing racquet sports like tennis. Prevention and management may involve proper techniques to minimize undue strain on the elbow. Severe cases might involve rest, anti-inflammatory medication, and potentially surgery.
Explanation:Tennis elbow, medically known as tendinitis, is a condition typically resulting from overuse of the elbow joint, which often occurs in racquet sports like tennis. This overuse leads to joint deterioration or damage to the tendons in the elbow, resulting in a microtrauma that initiates an inflammatory response. In severe cases, tendinitis can even result in a tendon tearing loose, necessitating surgical repair.
The connective tissue in the tendon, which doesn't have an abundant blood supply, heals slowly. Therefore, the prevention and management of tennis elbow might involve techniques of using the racquet to minimize undue torques and repetitive motion that can strain the elbow. For example, hitting tennis balls at the sweet spot on the racquet can minimize felt vibration or impact force on the body.
A person with severe pain from tendinitis, like tennis elbow, will often need to rest, take anti-inflammatory medication, and possibly even undergo surgery. People whose jobs or hobbies involve repeated similar movements are often most at risk for tendinitis. Therefore, it's important to use proper technique in sports and other activities to avoid undue stress on the joints and tendons.

The two bones that form the nasal septum are the ____________ and _____________ of the ethmoid.
Answer:
The answer is: vomer bone and perpendicular plate of ethmoid bone.
Explanation:
The nasal septum is the structure present inside the nose, that separates the left and the right nasal cavities and the nostrils. It is composed of bones and the hyaline cartilage.
The nasal septum consists of two bones: the vomer bone and, the perpendicular plate of ethmoid bone. The hyaline cartilage of the nasal septum is known as the septal nasal cartilage.
The nasal septum is formed by the perpendicular plate and the vomer bone of the ethmoid. These two structures, together with the septal cartilage, create a divide in the nasal cavity.
Explanation:The two bones that form the nasal septum are the perpendicular plate and the vomer bone of the ethmoid. The ethmoid bone is a unique, midline bone that contributes to the formation of various parts of the nasal cavity, including the roof, lateral walls, and nasal septum. The perpendicular plate of the ethmoid bone and the vomer bone come together to form the nasal septum, which splits the nasal cavity into left and right halves. The septal cartilage fills the space between these two bones, extending into the nose. In summary, the nasal septum structure is a collaboration of the vomer and perpendicular plate of the ethmoid bone, aided by the septal cartilage.

Explain how complement generally prevents microbes from causing disease.
Answer:
The complement system plays important role in body defense and provides innate and adaptive immune response to the body. The complement system is made up of many proteins found in the serum.
The complement system performs many roles like cell lysis, clearance of immune complex and opsonization which helps in removing the foreign molecule from blood and put them in spleen and liver for lysis.
Most of the components of complement are synthesized in the liver and binds to antigen-antibody complex to form membrane attack complex(MAC) which results in cell lysis.
Complement plays important role in phagocytosis of disease-causing microbes by phagocytic cells. By this way complement generally, prevent microbes from causing disease.
Explain why during peak, exhausting levels of activity glycolysis generates the greater amount of ATP compared to the mitochondria?
Answer:
The answer to this question lies in the number of steps, and substances, that are needed in order to yield ATP from ADP. While in anaerobic glycolysis pyruvic acid and lactic acid will yield their energy so that ADP can be re-synthetized into ATP, producing 2 molecules of ATP from that simple chain of reaction, aerobic glycolysis depends on the presence of oxygen, and several more chemical steps, chemical reactions, in order to finally yield all the ATPs it can yield.
Explanation:
When we are talking about intense training, like a sudden sprint, we are talking about the body needing ATP as fast as it possibly can get it so the muscles can move. Because of this immediacy, the body resorts first to its stores in muscle tissue and in the liver, to feed the anaerobic processes for ATP formation. The other process, called the Lactic Acid system, is the second of the anaerobic processes and its benefit is that while not requiring oxygen to produce ATP, it will use the stores of glycogen in the muscle and the liver, and through the chemical reactions of enzymes, it will produce enough ATP to power the exercise for at least a few minutes, without having to resort to the aerobic system. The number of steps taken to yield ATP are much lesser, and thus much more immediate, than in aerobic glycolysis.
Development of the testes in the embryo is due to:
A. Production of placental estrogen
B. Presence of Mullerian inhibiting hormone
C. Presence of a single Y chromosome.
D. Increased fetal FSH secretion
E. Effects of biochemical conversion of steroid precursors by the fetal adrenal.
Answer:
The best answer to the question: Development of the testes in the embryo is due to:___, would be, C: Presence of a single Y chromosome.
Explanation:
The subject of sexual differentiation into male, or female, during the prenatal, and especially embryonic stage, is still a matter of study and research. Although many of the processes are widely accepted and understood, studies show that there may be other factors involved in sexual differentiation. However, what has been known so far is that in the embryonic stage, the presence of TDF (testis-determining factor) is crucial to this determination. TDF is a product of the presence of the Y chromosome in the gene known as SRY. It has been seen that when this protein product is not presence, there will be no growth of the necessary parts for male differentiation from a female.
