1. Which bones do the rotator cuff help to stabilize?

• A. Radius and humerus
• B. Scapula and clavicle
• C. Humerus and scapula
• D. Ulna and radius

Correct answer: C

Rationale: The correct answer is C: Humerus and scapula. The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint. Specifically, the rotator cuff muscles help to stabilize the head of the humerus (the upper arm bone) within the shallow socket of the scapula (shoulder blade). This stabilizing action is crucial for maintaining shoulder joint function and preventing injuries. Choices A, B, and D are incorrect because the rotator cuff primarily stabilizes the humerus and scapula, not the radius, ulna, or clavicle.

2. What is the average normal body temperature in degrees Celsius?

• A. 30°C
• B. 32°C
• C. 35°C
• D. 37°C

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.

3. Which lobe of the brain is primarily responsible for auditory functioning?

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

Correct answer: B

Rationale: The correct answer is B: Temporal lobe. The temporal lobe of the brain is primarily responsible for processing auditory information, including sound perception, speech recognition, and language comprehension. Damage to the temporal lobe can lead to difficulties in hearing, understanding spoken language, and recognizing familiar sounds. Choices A, C, and D are incorrect because the frontal lobe is mainly associated with functions such as decision-making and personality, the occipital lobe is primarily responsible for processing visual information, and the parietal lobe is involved in sensory functions and spatial processing, not auditory functioning.

4. Which gland is located on top of the kidneys?

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

Correct answer: A

Rationale: The correct answer is the Adrenal gland. The adrenal glands are located on top of the kidneys. They produce hormones such as adrenaline and cortisol, which play essential roles in regulating metabolism, immune response, and stress in the body. The Thyroid gland, Pineal gland, and Pancreas are not located on top of the kidneys. The Thyroid gland is located in the neck, the Pineal gland in the brain, and the Pancreas behind the stomach.

5. What is the function of the stomach in the digestive system?

• A. To absorb nutrients
• B. To break down food
• C. To produce bile
• D. To store waste

Correct answer: B

Rationale: The correct answer is B: 'To break down food.' The stomach plays a crucial role in the digestive system by breaking down food using gastric acid and digestive enzymes. This process transforms the food into a semi-liquid mixture known as chyme, which is further digested in the small intestine. Choices A, C, and D are incorrect because the stomach does not primarily absorb nutrients, produce bile, or store waste. These functions are carried out by other organs in the digestive system such as the small intestine, liver, and large intestine, respectively.
