Question 4 of 5
The release of hormones from endocrine glands is most often controlled by
Correct Answer: C
Rationale: Hormone release often involves cAMP (second messenger from GPCRs, e.g., glucagon) and calcium (triggers exocytosis, e.g., insulin) common intracellular signals. Peptide hormones stimulate, not control release directly effectors. Calcium/glucose influence (e.g., insulin), but cAMP broadens scope. Sodium aids depolarization, not primary control. cAMP-calcium synergy distinguishes release mechanisms, critical for endocrine signaling, unlike hormone, substrate, or ion pairs.
Question 5 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.
