1. The shoulder is _________ to the elbow.

• A. posterior
• B. proximal
• C. distal
• D. medial

Correct answer: B

Rationale: Proximal refers to a position closer to the point of attachment or origin. In this case, the shoulder is closer to the point of attachment to the body compared to the elbow, making it proximal to the elbow. 'Posterior' refers to the back side of the body, 'distal' means farther away from the point of attachment, and 'medial' refers to the middle of the body. These terms do not accurately describe the relationship between the shoulder and the elbow in this context.

2. What is the function of the large intestine in the digestive system?

• A. To secrete digestive enzymes
• B. To absorb water and form solid waste
• C. To produce bile
• D. To transport nutrients

Correct answer: B

Rationale: The large intestine's primary function is to absorb water from the remaining indigestible food matter that enters it from the small intestine. This absorption process helps in forming solid waste (feces) by compacting the material and preparing it for excretion. The large intestine does not secrete digestive enzymes, produce bile, or transport nutrients. Therefore, option B, 'To absorb water and form solid waste,' is the correct function of the large intestine in the digestive system.

3. What is the primary role of the liver in the body?

• A. Producing insulin
• B. Detoxifying harmful substances
• C. Digesting food
• D. Storing energy

Correct answer: B

Rationale: The correct answer is B: Detoxifying harmful substances. While the liver does produce bile for digestion and stores nutrients like glycogen, its primary function is to filter and detoxify blood coming from the digestive tract before passing it to the rest of the body. Therefore, choices A, C, and D are incorrect. Producing insulin is mainly done by the pancreas, digesting food is primarily the role of the stomach and intestines, and storing energy is a function of various organs like muscles and fat cells.

4. The cheekbones are positioned ___________ to the nose.

• A. anterior
• B. proximal
• C. deep
• D. lateral

Correct answer: D

Rationale: The term 'lateral' refers to the direction away from the midline of the body. In this case, the cheekbones are situated to the sides of the nose, making them lateral to the nose. Therefore, 'lateral' correctly describes the position of the cheekbones in relation to the nose. Choices A, B, and C are incorrect: A. 'Anterior' means situated at or towards the front, which is not the correct description of the cheekbones in relation to the nose. B. 'Proximal' means situated nearer to the center of the body, which is not the correct description of the cheekbones' position in relation to the nose. C. 'Deep' refers to being situated further away from the surface, which is not the appropriate term to describe the cheekbones' position in relation to the nose.

5. Which part of the brain is responsible for controlling balance and coordination?

• A. Cerebellum
• B. Cerebrum
• C. Brainstem
• D. Medulla oblongata

Correct answer: A

Rationale: The cerebellum is the correct answer. It is responsible for controlling balance, coordination, and fine motor movements. The cerebrum is mainly associated with higher brain functions such as thinking and decision-making, not specifically balance and coordination. The brainstem is responsible for basic life functions like breathing and heartbeat, while the medulla oblongata is involved in regulating autonomic functions like breathing, heart rate, and blood pressure. Therefore, the cerebellum stands out as the key brain region for maintaining physical control and movement.
