1. What function is associated with the dermal layer of the skin?

• A. Sensory perception
• B. To provide support and structure to the skin
• C. Protection from UV rays
• D. Insulation

Correct answer: B

Rationale: The correct function associated with the dermal layer of the skin is to provide support and structure to the skin. The dermis is the thickest layer of the skin and is responsible for maintaining the skin's integrity and firmness. Choices A, C, and D are incorrect as sensory perception, protection from UV rays, and insulation are functions associated with other layers of the skin, such as the epidermis and subcutaneous tissue.

2. Which of the following hormones is secreted by the posterior pituitary gland?

• A. Growth hormone
• B. Luteinizing hormone
• C. Adrenocorticotropic hormone
• D. Antidiuretic hormone

Correct answer: D

Rationale: The correct answer is D: Antidiuretic hormone. Antidiuretic hormone (ADH), also known as vasopressin, is produced by the hypothalamus and stored in the posterior pituitary gland. It plays a key role in regulating the body's water balance by controlling the amount of water reabsorbed by the kidneys. Choices A, B, and C are incorrect because Growth hormone is produced by the anterior pituitary gland, Luteinizing hormone is produced by the anterior pituitary gland, and Adrenocorticotropic hormone is produced by the anterior pituitary gland.

3. Which of the following must the human body obtain from the environment in order to survive?

• A. Nitrogen
• B. Waste products
• C. Water
• D. Carbon dioxide

Correct answer: C

Rationale: The correct answer is C: Water. Water is essential for the human body to survive as it plays a crucial role in various physiological processes like digestion, circulation, and temperature regulation. Nitrogen is abundant in the atmosphere and is not directly obtained from the environment for survival. Waste products are materials that need to be eliminated from the body, not obtained for sustenance. Carbon dioxide is a byproduct of cellular respiration and is expelled from the body through breathing, not obtained as a nutrient.

4. Metabolism refers to all of the chemical reactions in an organism that support life. Is this statement true?

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The statement is true. Metabolism indeed refers to all of the chemical reactions in an organism that support life. It is essential for various processes in the body, including converting food into energy, building and repairing tissues, and eliminating waste products. Choice B is incorrect because metabolism does encompass all chemical reactions that sustain life. Choice C is incorrect as the definition of metabolism is clear. Choice D is incorrect as the statement provided is true.

5. The anatomical term that indicates a structure close to the surface is

• A. anterior
• B. proximal
• C. superficial
• D. superior

Correct answer: C

Rationale: The correct answer is 'superficial.' In anatomy, the term 'superficial' refers to a structure that is close to the surface of the body. Choice A, 'anterior,' refers to the front of the body, not specifically to depth. Choice B, 'proximal,' refers to a structure that is closer to the point of attachment or trunk of the body. Choice D, 'superior,' indicates a structure that is above or higher in position.
