1. Which part of the nervous system includes the femoral, radial, and ulnar nerves?

• A. Somatic
• B. Autonomic
• C. Sympathetic
• D. Parasympathetic

Correct answer: A

Rationale: The correct answer is A: Somatic. The femoral, radial, and ulnar nerves are all part of the somatic nervous system, responsible for controlling voluntary movements and sensory input. These nerves innervate muscles and skin throughout the body, allowing conscious control of movements and sensations. The somatic nervous system is distinct from the autonomic nervous system, which regulates involuntary bodily functions. Choices B, C, and D are incorrect because the autonomic nervous system (B) is responsible for involuntary functions, while the sympathetic (C) and parasympathetic (D) divisions are subdivisions of the autonomic nervous system, not the somatic nervous system.

2. Which gland is responsible for regulating metabolism and growth?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pineal gland

Correct answer: A

Rationale: The correct answer is the Thyroid gland. The thyroid gland is responsible for regulating metabolism and growth. It produces hormones such as thyroxine (T4) and triiodothyronine (T3), which play essential roles in controlling metabolic processes, growth, and development throughout the body. Choice B, the Pituitary gland, although important for hormone regulation, is not primarily responsible for regulating metabolism and growth. Choices C and D, the Adrenal gland and Pineal gland, respectively, have different functions and are not primarily involved in regulating metabolism and growth.

3. 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.

4. What is the role of the gallbladder in digestion?

• A. To produce bile
• B. To store and concentrate bile
• C. To break down fats
• D. To secrete digestive enzymes

Correct answer: B

Rationale: The gallbladder's primary function in digestion is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. While the gallbladder does not produce bile (Choice A) or secrete digestive enzymes (Choice D), it plays a crucial role in storing and releasing bile when needed. Therefore, the correct answer is B.

5. What is the function of the adrenal glands?

• A. To regulate blood sugar
• B. To produce hormones
• C. To produce red blood cells
• D. To filter blood

Correct answer: B

Rationale: The adrenal glands function to produce hormones such as adrenaline and cortisol. These hormones play essential roles in regulating metabolism, immune response, and the body's response to stress. Therefore, the correct answer is that the adrenal glands produce hormones. Choices A, C, and D are incorrect as regulating blood sugar is primarily done by the pancreas, producing red blood cells is the function of the bone marrow, and filtering blood is carried out by the kidneys, not the adrenal glands.
