5 Matching questions

  1. GH fxns
  2. Effects of glucagon on liver
  3. OT (oxytocin) release
  4. Evidence for NV hypothesis
  5. Secretin family
  1. a inc in glucose release, gluconeogenesis, glycogenolysis, ketogenesis:: dec in glycogenesis
  2. b stimulate growth, extracellular deposition of bones, lipases that convert triglycerides to FFAs and body fat
  3. c Secretin, glucagon, gastric inhibitory peptide (GIP), vasoactive intestinal peptide (VIP); share AA sequences; inc cAMP
  4. d interruption of vascular system altered horm secretion; reciprocal transplantation of pit gland between M and F rats indicated that hypothalamus controls AP fxn (not gender specific)
  5. e neuroendocrine reflex - result of sensory input to SC -> brain; neuron depolarization in AP of pars nervosa -> Ca entry -> exocytosis of OT; AP reach axon tips in 0.5-1.5m/s; ex of stimulus released coupling: rapid response

5 Multiple choice questions

  1. dopamine inhibits MSH release, dopamine present in hypo portal system
  2. neurotransmitter; inhibits prolactin release; agonists inhibit PRL release from AP, antagonists stimulate release; Hyperprolactinemia in 28% women with menstrual abnormalities, treat with dopamine agonists (parlodel, bromocryptine mesylate)
  3. Neoplastic tumor of hormone producing cells, most common in microadenonas
  4. GI absorption; storage in bone as Ca10(PO4)6(OH)2 (80% Ca in bone); relationship to P: [Ca] x [PO4] = K; PO4 stored in bone/tissue not carefully regulated
  5. hypoglycemic hormone that dec BSG levels, inc m/m of glucose into cells
