Question 1
Which of the following are functions of the skeletal system? (Select the ONE that does not apply.)
Correct Answer: C
Rationale: The correct answer is C, 'Conducting impulses.' The skeletal system's primary functions include supporting the body to maintain posture and provide structure, facilitating movement, protecting internal organs, and producing blood cells through hemopoiesis. Conducting impulses is a function of the nervous system, not the skeletal system.

Question 2
Which of the following are functions of the skeletal system? (Select one that does not apply.)
Correct Answer: C
Rationale: The correct answer is C, 'Conduct impulses.' The skeletal system's primary functions include supporting the body, hemopoiesis (blood cell production), and providing protection to internal organs. Conducting impulses is a function of the nervous system, not the skeletal system. The skeletal system serves as the framework for the body, enabling movement, protecting vital organs, producing blood cells, storing minerals, and supporting the overall structure of the body.

Question 3
What are the two functions of the male and female reproductive organs?
Correct Answer: C
Rationale: The male and female reproductive organs have two primary functions: the production of gametes (sperm in males and eggs in females) and the production of hormones. Gametes are essential for sexual reproduction, while hormones play a crucial role in regulating various physiological processes in the body, such as growth, development, and reproductive functions.

Question 4
Where do spermatozoa develop in men?
Correct Answer: A
Rationale: Spermatozoa develop within the seminiferous tubules of each testis. These tubules are responsible for the production of sperm through a process called spermatogenesis. While the vas deferens, ejaculatory ducts, and bulbourethral glands play essential roles in the transport and release of sperm, they are not involved in the actual development of sperm.

Question 5
Which hormones regulate testicular activity?
Correct Answer: D
Rationale: Testicular activity is regulated by both follicle-stimulating hormone (FSH) and luteinizing hormone (LH). FSH stimulates sperm cell production in the testes, while LH stimulates testosterone production by Leydig cells in the testes. Therefore, both FSH and LH are essential in controlling testicular activity.
