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. How does a transverse section divide the body?

• A. Into right and left regions
• B. Into upper and lower regions
• C. Into front and back regions
• D. Between the dorsal and ventral cavities

Correct answer: B

Rationale: A transverse section, also known as a cross-section, divides the body into upper and lower regions. This type of section cuts across the body horizontally, creating a division between the superior (upper) and inferior (lower) portions of the body. Choice A is incorrect as dividing the body into right and left regions is typically done by a sagittal section. Choice C is incorrect as dividing the body into front and back regions is usually achieved by a frontal section. Choice D is incorrect as it refers more to the relationship between dorsal and ventral cavities rather than the actual division of the body.

3. Which is a posterior feature of the human leg?

• A. Patella
• B. Quadriceps sartorius
• C. Triceps brachii
• D. Achilles tendon

Correct answer: D

Rationale: The correct answer is the Achilles tendon. The Achilles tendon is a strong tendon located at the back of the human leg, connecting the calf muscles to the heel bone. This positioning makes it a posterior feature, situated at the rear of the leg. The patella, also known as the kneecap, is positioned at the front of the leg, making it an anterior feature. The quadriceps sartorius are muscles located in the front of the thigh, not at the back of the leg. Additionally, the triceps brachii is a muscle found in the upper arm, not in the leg, making it an incorrect choice.

4. What is the function of the gallbladder in the digestive system?

• A. To produce bile
• B. To store and concentrate bile
• C. To detoxify harmful substances
• D. To regulate blood sugar

Correct answer: B

Rationale: The gallbladder's main function is to store and concentrate bile produced by the liver. Bile is essential for the digestion and absorption of fats in the small intestine. Therefore, the correct answer is B, as the gallbladder acts as a reservoir for bile rather than producing it. Choices A, C, and D are incorrect because the gallbladder does not produce bile, detoxify harmful substances, or regulate blood sugar in the digestive system.

5. The motor cortex is essential for monitoring and controlling body movements. Where is the motor cortex located within the brain?

• A. Top, middle portion of the parietal lobe
• B. Back of the head
• C. Front portion of the parietal lobe
• D. Around the auditory cortex

Correct answer: C

Rationale: The motor cortex is located in the frontal portion of the brain, specifically in the precentral gyrus of the frontal lobe. It plays a crucial role in planning, controlling, and executing voluntary movements. Choice A, 'Top, middle portion of the parietal lobe,' is incorrect because the motor cortex is not located in the parietal lobe but rather in the frontal lobe. Choice B, 'Back of the head,' is incorrect as it refers to the occipital lobe, not where the motor cortex is situated. Choice D, 'Around the auditory cortex,' is incorrect as the motor cortex is not located around the auditory cortex but in the frontal lobe, as mentioned earlier.
