Contraction in which the muscle length remains the same but the tension increases. ... -muscles do not always contract using 100% of their strength. The strength of a muscle's contraction depends on the amount of stimuli, the load placed on the muscle, and other factors.
The strength of a muscle contraction is determined by the size and number of motor units being stimulated.
Explanation:
30. The postganglionic sympathetic fibres in the nerve of the pterygoid canal originates
from?
A. The lesser petrosal nerve
B. Deep petrosal nerve
© Greater petrosal nerve
D. Chorda tympani
Answer:
The correct answer is B)Deep petrosal nerve
Explanation:
Postganglionic sympathetic fibers in the nerve of the pterygoid canal originate from the deep petrosal nerve. This corresponds to an internal carotid plexus and is formed by postganglionic fibers of the upper cervical ganglion; transports sympathetic postganglionic fibers directed to the blood vessels.
A liter IV bag is running at 50ml/hour. How long will it last?
Answer:120 hours
Explanation:six liters divided by 50 milliliters
Final answer:
To determine how long a 1-liter IV bag will last at a flow rate of 50ml/hour, divide the total volume by the flow rate, resulting in the IV bag lasting for 20 hours.
Explanation:
If a 1-liter IV bag is running at 50ml/hour, we can calculate how long it will last by dividing the total volume of the IV bag by the flow rate. The calculation is as follows:
Volume of IV bag = 1000 ml (since 1 liter = 1000 ml)
Flow rate = 50 ml/hour
Time = Volume / Flow rate
Time = 1000 ml / 50 ml/hour = 20 hours
Thus, the IV bag will last for 20 hours.
Five points of diluted hydrochloric acid weighs 2.79kg.calculate its specific gravity

Silver does not react with [tex]HCl[/tex] and the reason behind the fact because, like other reactive metals, silver can not displace hydrogen from [tex]HCl[/tex]silver is below hydrogen in the reactivity series and thus can not displace it.silver does not react with dilute [tex]HCl[/tex] but definitely reacts with concept.
The reaction of silver with hydrochloric acid has no result as this metal does not dissolve in hydrochloric acid because it is covered with a thin layer of silver chloride if you add a free oxygen of the solution in the form of hydrogen peroxide the reaction beads to the oxidation of the silver to silver chlorine.

Final answer:
The specific gravity calculation of a hydrochloric acid solution given its mass (2.79kg) and volume (1L) leads to a specific gravity of 2.79, assuming the solution's density is directly computed from these values.
Explanation:
The question posed was: Five points of diluted hydrochloric acid weighs 2.79kg. Calculate its specific gravity volume of HCl is 1L. However, there seems to be a misunderstanding or misinterpretation in the phrasing of the question as it appears to mix two distinct questions - calculating specific gravity and involving a density-related calculation with given mass and volume, which don't fully align to the standard approach of addressing specific gravity directly.
Specific gravity, in general, is the ratio of the density of a substance to the density of a reference substance; generally, water for liquids, which has a density of 1 g/cm³ (or equivalently 1000 kg/m³). Assuming the question aims to find the specific gravity of this particular 'diluted' hydrochloric acid solution, given its mass and volume, one would first calculate its density by dividing mass by volume, then compare this density to that of water to find its specific gravity. However, there is a lack of clarity regarding the 'five points' mentioned and whether 'diluted' refers to a specific concentration.
Assuming a straightforward calculation where '2.79kg' is the total mass of the hydrochloric acid solution and '1L' is its volume, converting 2.79kg into grams (2790g for compatibility with the common density unit g/mL), and then dividing by the volume in mL (1000mL since 1L=1000mL), the density of the hydrochloric acid solution would be 2.79 g/mL. The specific gravity is then this density divided by the density of water (1 g/mL), yielding a specific gravity of 2.79.
What is the connection between anatomy and physiology and coding and billing?
Answer:
The relationship between anatomy and physiology are that they will always correlate with each other anatomy being the study of the actual physical organs and their structure as well as their relationship to each other. While physiology studies how those organs work to function the whole body as organ systems.
Explanation:
Anatomy and physiology knowledge is essential for accurate medical coding and billing, as it provides the necessary understanding of medical terminology, which is used to categorize health services and diagnoses for billing.
The connection between anatomy and physiology with coding and billing in the medical field is foundational to the healthcare industry. Anatomy, which focuses on the structure of the body, and physiology, which centers on the function of these structures, are crucial for understanding medical terminology. In coding and billing, precise knowledge of medical terms derived from anatomy and physiology is required to accurately describe and categorize healthcare services and diagnoses for insurance and billing purposes.
When coding medical procedures and diagnoses, professionals draw on their understanding of where in the body the medical term is referencing, as well as how that part of the body works. This ensures that medical services are billed correctly and efficiently. For students in healthcare-related fields, gaining expertise in anatomy and physiology not only supports their ability to comprehend medical codes but also empowers them to make informed health decisions and understand the broader context of medical news, devices, and procedures.

Which of the following is an example of medical negligence?
Final answer:
Medical negligence occurs when a healthcare professional causes harm to a patient by failing to follow established protocols or using known faulty equipment, breaching the principle of nonmaleficence. Liability can fall on healthcare workers, equipment manufacturers, or institutions following flawed procedures.
Explanation:
An example of medical negligence might involve a healthcare professional who fails to adhere to established protocols, resulting in harm to a patient. For instance, if a surgeon performs an operation with knowledge that the equipment they are using is faulty, and this leads to patient injury, that could be construed as negligence. Similarly, if a hospital follows a flawed procedure that is known to be ineffective or dangerous and patients are harmed as a result, this could also be considered medical negligence. Responsibility can be a complex issue, with potential liability falling on healthcare workers, manufacturers of medical equipment, or even the protocols themselves.
Consider the principle of nonmaleficence, which dictates that clinicians should not cause unnecessary harm to patients. If a healthcare provider administratively or clinically harms a patient through a lack of due diligence or outright disregard for safe practices, this would breach the principle of nonmaleficence—a cornerstone of medical ethics.
In contrast, a counter example from a different sector might be a case where a car manufacturer is aware of a brake system defect but proceeds to sell the vehicle regardless. If accidents occur due to the known defect, the manufacturer would be held liable. While this is not directly an example of medical negligence, it illustrates the broader concept of negligence and accountability.
