Anatomy

1. What is the difference between a sensory neuron and a motor neuron?

Correct answer: A

Rationale: The correct answer is A because sensory neurons are responsible for carrying signals from sensory receptors towards the central nervous system (brain and spinal cord), allowing us to perceive sensations such as touch, taste, smell, sight, and sound. On the other hand, motor neurons carry signals from the central nervous system to muscles and glands, enabling movement and responses. Therefore, sensory neurons carry signals away from the brain, while motor neurons carry signals towards the brain, making option A the most accurate choice among the options provided.

2. St. Raphael Medical Center just opened its new Performance Improvement Department. Ms.

Correct answer: B

Rationale: The correct answer is B: 'Identify the values of the department.' When a new department is established, it is important to define its core values, beliefs, and principles to guide its operations. This helps create a shared understanding among staff and stakeholders about the department's purpose and priorities. By identifying the values of the Performance Improvement Department at St. Raphael Medical Center, employees can align their actions with the department's mission and goals, fostering a cohesive and effective work environment. Options A, C, and D are not directly related to establishing the foundational values of a new department, making them less relevant in this context.

3. Which structure surrounds individual muscle fibers, providing support and aiding in the transmission of force generated during muscle contraction?

Correct answer: b

Rationale: The correct answer is B: Endomysium. Endomysium is the connective tissue layer that surrounds individual muscle fibers within a muscle. It plays a crucial role in supporting the muscle fibers and aiding in the transmission of force generated during muscle contraction. Tendons (option A) connect muscle to bone and do not surround individual muscle fibers. Perimysium (option C) surrounds bundles of muscle fibers, while epimysium (option D) envelops the entire muscle. Therefore, endomysium is specifically responsible for surrounding and supporting individual muscle fibers, making it the most fitting answer.

4. Which of the following is NOT a symptom of asthma, a chronic respiratory condition?

Correct answer: D

Rationale: The correct answer is D: "Fever." Fever is not a symptom commonly associated with asthma. Asthma symptoms typically include wheezing (A), difficulty breathing (B), and chest tightness (C). Wheezing is a high-pitched whistling sound that occurs during breathing, while difficulty breathing refers to the feeling of not getting enough air. Chest tightness is a common sensation of pressure or constriction in the chest. Fever is not a typical symptom of asthma but may occur in other respiratory conditions or infections. Therefore, fever is the correct answer as it does not align with the typical symptom profile of asthma.

5. What is the main component of sweat?

Correct answer: C

Rationale: Rationale: - Sweat is primarily composed of water, making up the majority of its content. Water helps regulate body temperature by evaporating from the skin's surface, which cools the body down. - While sweat does contain small amounts of other substances like urea, glucose, and electrolytes, water is the main component that is secreted by sweat glands to help regulate body temperature during physical activity or in response to heat.

6. During gas exchange in the alveoli, what happens to oxygen?

Correct answer: B

Rationale: During gas exchange in the alveoli, oxygen is absorbed from the alveoli into the bloodstream. In the alveoli, oxygen diffuses across the thin walls of the alveoli and into the surrounding capillaries where it binds to hemoglobin in red blood cells. This oxygen-rich blood is then transported to the body's tissues for cellular respiration. Therefore, option B is correct as it accurately describes the direction of oxygen movement during the process of gas exchange in the lungs.
