Answer:
C. Prevents the development of female internal reproductive organs in an XY male.
Explanation:
Antimüllerian hormone, also known as Mullerian inhibiting hormone, is a protein responsible for preventing the formation of Müllerian ducts in a male embryo (XY). Müllerian ducts, also known as paramesonephric ducts, are structures that are present in the embryo and give rise to female internal genitals if they are a girl or remain in their vestigial form if they are a boy. This vestigial form, which is formed in boys, is caused by the presence of antimullerian hormone.
The laryngeal prominence is an enlarged region on the anterior surface of the ________ cartilage and is nicknamed __________.
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.
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.Which of the following neurotransmitters is a biogenic amine but not a catecholamine?
A. Norepinephrine.
B. Serotonin
C. Dopamine
D. Epinephrine.
E. All are catecholamines
Answer:
B. Serotonin is a biogenic amine but not a catecholamine.
Explanation:
Catecholamines are the molecules which have an aminolaterral chain with a chatecol and an amino group on their structure. Also, catecholamines are derived from an aminoacid called tyrosine. Instead, Serotonin is derived from an aminoacid called tryptophan and its structure does not contain the chemical compounds to be a catecholamine.
Serotonin (B) is the neurotransmitter that is a biogenic amine but not a catecholamine; it is synthesized from tryptophan rather than tyrosine, which is the precursor for catecholamines like norepinephrine, dopamine, and epinephrine.
Explanation:The neurotransmitter that is a biogenic amine but not a catecholamine is Serotonin (B). Serotonin is synthesized from the amino acid tryptophan and is a key neurotransmitter in the serotonergic system, which differs from the catecholamine system that includes norepinephrine, dopamine, and epinephrine. These catecholamines are derived from the amino acid tyrosine and are part of the adrenergic neurotransmitter system, meaning they are involved in the adrenergic response in the body.
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.
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.
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.

State and describe the function of the three main types of lymphocytes in our body.
Explanation:
Lymphocytes are the type of the white blood cell which function as a part of immune system.
Types of Lymphocytes:
T cells
T cells are developed in thymus gland. The specialized molecule of T-cell receptor is located on surface of cell. The molecule is important in the immunity as it recognizes the antigens and thus it to bind to them.
B cells
B cells are important part of immune system. They mature in bone marrow of the humans, and in bursa organ of the birds. The cells have a protein on the surface which is known as B-cell receptor. The protein recognizes and attaches to the specific antigens.
Natural killer cells
Natural killer cells are the lymphocytes which are known to be cytotoxic. They have ability to kill the other cells in the body. The cells are important part of immune system because these cells are able to recognize infected cells.
B lymphocytes are cells that are initially produced in the yolk sac, then in the liver (during fetal life), and later in the bone marrow. They are responsible for ensuring the so-called humoral immunity, which stands out for the immune response made by the production of antibodies. These antibodies are capable of neutralizing or even destroying antigens. In addition to antibody production, B lymphocytes act as immune memory cells. These cells are able to react quickly to a new infection with the same antigen. As such, they ensure faster and more effective protection.
T lymphocytes originate from lymphoid progenitor cells found in the bone marrow. These cells leave the marrow towards the thymus. T helper lymphocytes guarantee the differentiation of B lymphocytes into plasma cells, and are therefore important for antibody production. Suppressor T lymphocytes terminate the humoral response, that is, antibody production. T lymphocytes are estimated to represent 65% to 75% of lymphocytes present in a person's blood.
NK cells (also a lymphocyte), or natural killer cells, are part of the innate immune system. These cells are able to distinguish infected or tumor cells and attack them without stimulation. Its immune response is nonspecific, unlike T and B lymphocytes, which produce responses by antigen action.
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.

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.

Do you believe it is ethical to prescribe expensive drugs to
less wealthy patients, even if the drug is better quality than
cheaper drugs?
Answer:
When talking about medical ethics, the first thing that must be taken into account is that there are four major basic principles that direct medical practice, and in general, the practice of all healthcare professionals. These are: autonomy, justice, beneficence and non-maleficence. These four are the core principles that ensure that a doctor will always do the best he can in regards to the patient, and for the benefit of the patient.
Unfortunately, these principles do not always apply to the pharmaceutical industry, whose ideas are set more on making profit, while at the same time procuring chemical compounds that benefit the health of patients. However, they do not take into consideration the means a patient may, or may not have, to acquire the elements.
In the case of the doctor, however, this is another matter altogether as he must seek to do what is best for the patient, given the four major principles of medical ethics. In particular, the doctor must apply here, in this case, the principles of beneficence and non-maleficence and he must prescribe the expensive drugs to a patient who have less means if he considers that they are absolutely the best for the health of the patient, and that there is absolutely no other choice when looking at pharmaceutical options. He must first evaluate if a cheaper medication could not achieve the same results, and benefit both the health situation, and income situation, of the patient. If these two are considered, and the answer is: there are no other possibilities, then I say it is ethical. If the decision is taken based on anything other than the benefit of the patient, then, it would be absolutely unethical.
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.

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.

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.
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.
In people who engage in regular vigorous exercise, RMR may account for a larger proportion of daily caloric need.

The capillaries perform the transport function of the circulatory system.
a. True
b. False
Answer:
The best answer to the question: The capillaries perform the transport function of the circulatory system, would be: false.
Explanation:
Although the term "transport" is used loosely here, the truth is that arteries, veins, arterioles and capillaries perform the function of conducting blood, which is the true carrier of everything that comes and goes from and to the tissues, to and from the places where this blood is needed. In that sense, most people say that capillaries, arteries, veins, and other vessels perform the function of "transport", but in essence transporting means literally carrying, and the one tissue that has that capacity in the circulatory system is blood, and it is blood that "transports", while the vessels conduct blood so that its function can be performed.
The metacarpals articulate with the

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.

The function of surfactant is to:
a. transport oxygen from the air to the blood.
b. transport carbon dioxide from the blood to the air.
c. prevent each alveolus from collapsing as air moves in and out during respiration.
d. trap foreign particles as they enter the bronchial tree.
Answer:
c. prevent each alveolus from collapsing as air moves in and out during respiration.
Explanation:
In the lungs the exchange of gases takes place with the help of numerous tiny air sacs called alveoli. The alveoli collectively have large surface area which is required for efficient gas exchange. Surfactant is a complex of six lipids and four proteins that helps the alveoli to maintain their structure. It reduces surface tension at air-liquid interface within the lungs and make alveoli more stable. Without it the alveoli would collapse into each other during exhalation process which would form larger air sacs with smaller surface area. It is secreted by epithelial type II cells in alveolar space.
Babies born without sufficient surfactant face difficulty in breathing, become tired and do not get enough oxygen. They suffer from respiratory distress syndrome or hyaline membrane 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.
