Endocrine System Questions and Answers PDF Questions
Question 1 of 5
What happens during Diabetes insipidus?
Correct Answer: B
Rationale: Diabetes insipidus results from ADH deficiency or renal resistance, impairing water reabsorption, causing dilute urine and thirst. Excess GH is gigantism, other options are absent. Renal ADH unresponsiveness distinguishes it, critical for fluid balance disorders, contrasting with growth or pituitary excess conditions.
Question 2 of 5
The pituitary hormone that stimulates the male testes to produce sperm and stimulates the development of the follicle in the female on a monthly cycle is:
Correct Answer: D
Rationale: Follicle-stimulating hormone (FSH) from the anterior pituitary stimulates spermatogenesis in testes and follicle growth in ovaries monthly. Growth hormone (GH) drives body growth, not gametes. Luteinizing hormone (LH) triggers testosterone and ovulation, not sperm/follicle initiation. Prolactin aids lactation. FSH's reproductive specificity distinguishes it, essential for fertility, unlike growth or ovulation hormones.
Question 3 of 5
Which of the following statements regarding pituitary hormones is false?
Correct Answer: B
Rationale: The hypothalamus synthesizes oxytocin and ADH, stored in the posterior pituitary true. Luteinizing hormone (LH) triggers ovulation and progesterone/estrogen production true. FSH/LH hyposecretion causes sterility true. ADH, however, reduces urine volume by increasing water reabsorption, raising blood volume, not decreasing it making B false. This error distinguishes ADH's role in osmoregulation, critical for fluid balance, contrasting with diuretic effects.
Question 4 of 5
Tropic hormones:
Correct Answer: C
Rationale: Tropic hormones (e.g., TSH, ACTH) from the anterior pituitary stimulate other endocrine glands to release hormones, regulating their activity. Pineal (melatonin) and thymus (thymosin) aren't primary targets, and nervous tissue isn't hormonally stimulated. This gland-targeting role distinguishes tropic hormones, vital for endocrine coordination, contrasting with direct tissue effects.
Question 5 of 5
The two regulatory systems of the body are the endocrine system and the
Correct Answer: A
Rationale: The endocrine and nervous systems regulate body functions: endocrine via hormones (slow, widespread), nervous via neurons (fast, specific). Immune defends, circulatory transports, respiratory oxygenates supportive, not regulatory. This dual control distinguishes them, key to coordination, contrasting with protective or transport systems.
