Endocrine System Questions and Answers PDF Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The release of cortisol is stimulated by
Correct Answer: D
Rationale: Adrenocorticotropic hormone (ACTH) from the anterior pituitary stimulates adrenal cortisol release, managing stress/metabolism. Aldosterone (adrenal) and angiotensin (RAAS) regulate fluid, ADH controls water not cortisol. ACTH's specific role distinguishes it, key to the HPA axis, contrasting with fluid-regulating hormones.
Question 5 of 5
The hormone that maintains blood sugar level is secreted by which gland?
Correct Answer: C
Rationale: The pancreas secretes insulin and glucagon to maintain blood sugar: insulin lowers it by promoting uptake, glucagon raises it via liver glucose release. Pineal (melatonin), pituitary (GH, ACTH), and adrenal (adrenaline) glands affect metabolism indirectly not sugar directly. Pancreas's dual hormonal role distinguishes it, key to glucose homeostasis, contrasting with stress or growth regulators.
