Endocrine System Questions Questions
Question 1 of 5
Identify the hormone(s) produced by the hypothalamus.
Correct Answer: D
Rationale: Hypothalamus produces oxytocin (labor), ADH (water balance), and releasing/inhibiting hormones (e.g., TRH, GHRH) all regulate pituitary. Oxytocin/ADH alone understate releasing hormones control anterior pituitary too. All-inclusive option distinguishes hypothalamic diversity, key to endocrine orchestration, unlike partial lists.
Question 2 of 5
Identify a hormone that increases metabolic rate.
Correct Answer: A
Rationale: Thyroid hormones (T3/T4) increase metabolic rate boosting cellular energy use, heat production. Calcitonin (thyroid) lowers calcium, not metabolism. Aldosterone (adrenal) manages sodium, not rate. PTH (parathyroid) raises calcium, minimal metabolic effect. Thyroid's metabolic surge distinguishes it, critical for energy regulation, unlike calcium or electrolyte hormones.
Question 3 of 5
Epinephrine and norepinephrine from the adrenal medulla will produce the same results as the nervous system.
Correct Answer: A
Rationale: Epinephrine/norepinephrine mimic sympathetic nervous system raising heart rate, glucose, alertness fight-or-flight synergy. Parasympathetic (rest/digest) opposes slows heart, digestion focus. Somatic controls voluntary muscles, not visceral. Central (CNS) governs, not mimics. Sympathetic alignment distinguishes catecholamines, critical for stress response, unlike opposing, voluntary, or oversight systems.
Question 4 of 5
Which of the following is NOT true of Cushing syndrome?
Correct Answer: D
Rationale: Cushing syndrome, from cortisol excess (adrenal cortex hypersecretion), causes trunk obesity, moon face, and buffalo hump not hyposecretion, which is Addison's. Basic blood pH (alkalosis) can occur from mineralocorticoid effects, true in severe cases. Hyposecretion contradicts excess defines it. Hypersecretion basis distinguishes Cushing's, key to its phenotype, unlike pH or hypo-error.
Question 5 of 5
Which of the following is NOT a possible effect of anabolic steroid use?
Correct Answer: D
Rationale: Anabolic steroids (testosterone-like) can cause breast enlargement (gynecomastia), balding (androgenetic), acne (sebaceous stimulation), and stunted growth (epiphyseal closure) all possible. No effect listed is impossible all occur variably. Comprehensive impact distinguishes steroid side effects, key to misuse risks, unlike excluding any listed outcome.
