5 Matching questions

  1. Fxn of GI hormones in digestive movements
  2. Cells and hormones of islets of Langerhans
  3. Factors affecting AVP release: blood volume/pressure
  4. Regulation of PTH release
  5. Glucagon like peptide-1 (GLP-1)
  1. a intestinal peptide encoded in proglucagon gene; produced by L cells of the intestine; stimulates insulin release in presence of glucose and suppresses glucagon secretion
  2. b AVP less sensitive than response to changes in osmolality, 5% dec in BP, 8% dec in BV; important with hemorrhage and blood loss, location of arterial baroreceptors: aortic arch, carotid sinus, lt atrium
  3. c B cells (insulin) a cells (glucagon) D cells (SST) F cells (PP, pancreatic polypeptide)
  4. d low Ca2+ stimulates, high Ca2+ inhibits, 1,25(OH)2D3 inhibits PTH synthesis
  5. e enzye, acid/base secretion; smooth muscle contraction; horm release from pancreatic islets; growth promoting actions

5 Multiple choice questions

  1. paraventricular nucleus, supraoptic nucleus, preoptic nucleus (PON)
  2. endogenous cannabinoid receptor; agonists that stimulate appetite; Leptin inhibits anandamide induced feeding
  3. about 10mg/ml; free Ca biologically active; low Ca causes tetany (twitches)
  4. in pars intermedia
  5. osmoregulate, contractile regulation (vasopressin-osmo, OT -contractile activity: uterine, milk release, orgasm); Vasopressin - antidiuretic, ADH, increase permeability of collecting ducts to water
