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 many bones are in the human foot?

• A. 6
• B. 16
• C. 26
• D. 36

Correct answer: C

Rationale: The correct answer is C: 26. The human foot consists of 26 bones, including tarsal bones, metatarsal bones, and phalanges. These bones collaborate to offer support, flexibility, and stability for various activities like standing, walking, and running. Choice A (6) is incorrect as it is too low for the number of bones in the human foot. Choice B (16) is incorrect as it underestimates the actual number of bones in the foot. Choice D (36) is incorrect as it overestimates the number of bones in the human foot.

3. 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.

4. Which part of the brain is involved in processing visual information?

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

Correct answer: C

Rationale: The occipital lobe, located at the back of the brain, is primarily responsible for processing visual information received from the eyes. It plays a crucial role in interpreting and making sense of the visual stimuli perceived by the eyes, such as shapes, colors, and movement. This region is essential for visual perception and is specialized for processing and analyzing visual input, making it the correct answer. The frontal lobe is primarily involved in higher cognitive functions like decision-making and problem-solving, not visual processing. The parietal lobe is more related to sensory processes and spatial awareness, while the temporal lobe is primarily involved in processing auditory information and memory, not visual processing.

5. Which of the following structures regulates the transport of substances in and out of a cell?

• A. Nucleus
• B. Cell membrane
• C. Cytoplasm
• D. Mitochondria

Correct answer: B

Rationale: The cell membrane, also known as the plasma membrane, is responsible for regulating the transport of substances in and out of the cell. It acts as a selective barrier, allowing the passage of certain molecules while restricting others. This selective permeability helps maintain homeostasis within the cell by controlling the movement of essential substances like nutrients and waste products. The nucleus (Choice A) is the organelle that houses the cell's genetic material and is not directly involved in regulating substance transport. Cytoplasm (Choice C) is the gel-like substance that fills the cell and does not play a direct role in regulating substance transport. Mitochondria (Choice D) are responsible for energy production in the cell through cellular respiration and are not primarily involved in substance transport.
