Assess students' recall of the major human endocrine glands and their primary hormones; students should be able to identify gland locations (hypothalamus, pituitary—anterior/posterior, thyroid, parathyroids, adrenal cortex/medulla, pancreas islets, pineal, ovaries, testes), name the principal hormones each produces (e.g., ADH/oxytocin, T3/T4, PTH, cortisol, epinephrine, insulin/glucagon, melatonin, estrogen/testosterone) and state each hormone's main physiological role in one sentence.
