1. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

• A. 55 beats per minute and 75 over 60 mm Hg
• B. 72 beats per minute and 120 over 80 mm Hg
• C. 100 beats per minute and 140 over 100 mm Hg
• D. 160 beats per minute and 100 over 70 mm Hg

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

2. Where would you be likely to find a Schwann cell?

• A. In the digestive system
• B. In the nervous system
• C. In the skeletal system
• D. In the muscular system

Correct answer: B

Rationale: Schwann cells are a type of neuroglia found in the peripheral nervous system. They are responsible for producing the myelin sheath around axons of neurons, which helps with the conduction of nerve impulses. Therefore, Schwann cells are typically found in the nervous system. Choices A, C, and D are incorrect because Schwann cells are specifically associated with the nervous system and are not found in the digestive, skeletal, or muscular systems.

3. Which of the following statements is anatomically correct?

• A. The knee is distal to the ankle.
• B. The heart is inferior to the diaphragm.
• C. The hip is proximal to the knee.
• D. The wrist is proximal to the elbow.

Correct answer: C

Rationale: The term 'proximal' refers to a body part being closer to the center of the body or a point of reference. In this case, the hip is closer to the center of the body compared to the knee, which makes the statement anatomically correct. Choice A is incorrect as the knee is proximal to the ankle. Choice B is incorrect as the heart is superior to the diaphragm. Choice D is incorrect as the elbow is proximal to the wrist.

4. Which gland controls Calciferol?

• A. Thyroid
• B. Pituitary
• C. Parathyroid
• D. Hypothalamus

Correct answer: C

Rationale: Calciferol, commonly known as Vitamin D, is regulated by the parathyroid gland, not the thyroid, pituitary, or hypothalamus. The parathyroid gland plays a crucial role in maintaining calcium and phosphorus balance in the body by regulating the production of calcitriol, the active form of Vitamin D. This hormone helps in the absorption of calcium from the intestines and its reabsorption in the kidneys to maintain proper calcium levels in the blood. Therefore, the correct answer is the Parathyroid gland (Choice C). Choices A, B, and D are incorrect as they do not have a direct role in controlling Calciferol.

5. What is the role of the large intestine in the digestive system?

• A. Absorbing nutrients
• B. Absorbing water and forming solid waste
• C. Breaking down fats
• D. Secreting digestive enzymes

Correct answer: B

Rationale: The correct answer is B: Absorbing water and forming solid waste. The large intestine plays a crucial role in absorbing water from the remaining indigestible food matter and forming solid waste (feces) to be excreted from the body. This process helps in maintaining the body's fluid balance and eliminating waste efficiently. Choices A, C, and D are incorrect because the large intestine is not primarily responsible for absorbing nutrients, breaking down fats, or secreting digestive enzymes. These functions are mainly carried out in the small intestine.
