1. Which of the following statements is anatomically correct?

• A. The knee is distal to the ankle.
• B. The heart is inferior to the diaphragm.
• C. The hip is proximal to the knee.
• D. The wrist is proximal to the elbow.

Correct answer: C

Rationale: The term 'proximal' refers to a body part being closer to the center of the body or a point of reference. In this case, the hip is closer to the center of the body compared to the knee, which makes the statement anatomically correct. Choice A is incorrect as the knee is proximal to the ankle. Choice B is incorrect as the heart is superior to the diaphragm. Choice D is incorrect as the elbow is proximal to the wrist.

2. The lateral side of the right knee would be ___________.

• A. the kneecap
• B. closest to the left knee
• C. farthest from the left knee
• D. on the underside of the knee

Correct answer: C

Rationale: The lateral side of the right knee is the side that is farthest from the left knee when looking at the knee joint from the front. The term 'lateral' refers to the side of the body that is farther away from the midline or center of the body. In this case, the lateral side of the right knee is on the outer side of the knee joint, away from the other knee. Choice A is incorrect as the kneecap is located at the front of the knee. Choice B is incorrect as it describes the medial side, not the lateral side. Choice D is incorrect as it refers to the underside, which is not related to the lateral aspect of the knee.

3. What is the role of enzymes in the body?

• A. To produce energy
• B. To speed up chemical reactions
• C. To transport molecules
• D. To repair tissues

Correct answer: B

Rationale: Enzymes are biological catalysts that facilitate and speed up chemical reactions in the body. They do not produce energy but enable various processes such as digestion and metabolism by lowering the activation energy required for reactions to occur. Choice A is incorrect because enzymes do not produce energy themselves but assist in energy production through reactions. Choice C is incorrect as enzymes do not primarily function in transporting molecules, although some may have a role in specific transport processes. Choice D is incorrect as the primary role of enzymes is not to repair tissues, but rather to catalyze biochemical reactions.

4. Which lobe of the brain is primarily responsible for processing sensory information related to touch, temperature, and body position?

• A. Frontal lobe
• B. Parietal lobe
• C. Occipital lobe
• D. Temporal lobe

Correct answer: B

Rationale: The parietal lobe is primarily responsible for processing sensory information related to touch, temperature, and body position. It plays a crucial role in interpreting sensations from different parts of the body, including proprioception, which is the awareness of body position. The frontal lobe is more associated with functions like decision-making and personality, the occipital lobe is primarily involved in visual processing, and the temporal lobe is responsible for auditory processing and memory. Therefore, the parietal lobe is the correct answer for this question.

5. Which muscle is responsible for the extension of the elbow?

• A. Biceps brachii
• B. Triceps brachii
• C. Deltoid
• D. Pectoralis major

Correct answer: B

Rationale: The correct answer is B: Triceps brachii. The triceps brachii muscle is responsible for extending the elbow joint. It is located on the back of the upper arm and acts in opposition to the biceps brachii, which is responsible for elbow flexion. The deltoid muscle is primarily responsible for shoulder abduction, not elbow extension. The pectoralis major muscle is involved in movements of the shoulder joint, not the elbow.
