1. Which gland is located superior to the kidney?

• A. Pituitary
• B. Adrenal
• C. Hypothalamus
• D. Pancreas

Correct answer: B

Rationale: The adrenal gland is located superior to the kidney. Each kidney is surrounded by an adrenal gland, also known as the suprarenal gland, situated on top of the kidneys. The pituitary gland (A) is located in the brain, while the hypothalamus (C) is also in the brain, above the pituitary gland. The pancreas (D) is located in the abdomen, near the stomach and small intestine, not superior to the kidney.

2. Which of the following is not part of the axial skeletal system?

• A. the skull
• B. the ribs
• C. the breastbone
• D. the radius

Correct answer: D

Rationale: The correct answer is D, the radius. The axial skeleton comprises bones located along the central axis of the body. It includes the skull, ribs, breastbone (sternum), vertebrae, and sacrum. The radius, on the other hand, is a bone of the forearm, part of the appendicular skeleton. The appendicular skeleton consists of the bones of the limbs and their girdles, not the central axial bones.

3. In the human body, the ribs are ___________ to the lungs.

• A. medial
• B. superior
• C. anterior
• D. deep

Correct answer: C

Rationale: The correct answer is 'C: anterior.' The term 'anterior' refers to a position in front of or toward the front of the body. In this case, the ribs are positioned in front of the lungs when considering the anatomical position. The term 'medial' means toward the midline of the body, 'superior' means above or higher in position, and 'deep' refers to a position farther from the surface or external part. Therefore, the most appropriate choice is 'anterior' when describing the relationship between the ribs and the lungs.

4. What is the primary function of the adrenal glands?

• A. To produce insulin
• B. To regulate metabolism and stress response
• C. To fight infections
• D. To regulate blood pressure

Correct answer: B

Rationale: The primary function of the adrenal glands is to regulate metabolism and the body's stress response. The adrenal glands produce hormones like cortisol and adrenaline that play a vital role in managing metabolism, immune response, and stress levels. Choice A is incorrect because insulin is produced by the pancreas, not the adrenal glands. Choice C is incorrect because fighting infections is primarily the role of the immune system. Choice D is incorrect as the regulation of blood pressure involves organs like the heart, kidneys, and blood vessels, not the adrenal glands.

5. Which of the following is an organ of the respiratory system?

• A. Pancreas
• B. Brain
• C. Urethra
• D. Larynx

Correct answer: D

Rationale: The larynx is a vital organ of the respiratory system, responsible for producing sound and connecting the pharynx to the trachea. It plays a crucial role in breathing, swallowing, and vocalization. The brain, pancreas, and urethra are not part of the respiratory system; the brain is part of the nervous system, the pancreas is part of the digestive system, and the urethra is part of the urinary system. Therefore, the correct answer is the larynx.
