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 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.

3. When an individual is under stress, hormones are released. Which of the following is not one of the locations where hormones are released when under stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not a location where hormones are typically released during stress. It primarily regulates calcium levels in the blood through the release of parathyroid hormone (PTH). On the other hand, the adrenal cortex releases hormones like cortisol in response to stress, the posterior pituitary releases oxytocin and antidiuretic hormone, and the hypothalamus plays a crucial role in coordinating stress responses through the release of corticotropin-releasing hormone (CRH). Therefore, the parathyroid gland is the correct answer as it is not directly involved in the stress response pathway.

4. Which vitamin is essential for blood clotting?

• A. Vitamin C
• B. Vitamin K
• C. Vitamin D
• D. Vitamin B12

Correct answer: B

Rationale: Vitamin K is essential for blood clotting as it is necessary for the synthesis of proteins involved in the coagulation process, such as clotting factors. Without sufficient Vitamin K, the blood may not clot properly, leading to excessive bleeding. Vitamin C is important for collagen synthesis and immune function, Vitamin D is essential for calcium absorption and bone health, and Vitamin B12 is crucial for red blood cell formation and neurological function. However, when it comes to blood clotting, Vitamin K plays a vital role.

5. Which of the following locations is not involved in the release of hormones during stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not involved in the release of hormones during stress. It is responsible for regulating calcium levels in the blood by secreting parathyroid hormone. During stress, the adrenal cortex, posterior pituitary, and hypothalamus play crucial roles in releasing stress hormones like cortisol, adrenaline, and oxytocin. Therefore, the correct answer is the parathyroid gland, as it is not directly associated with the release of stress-related hormones.
