EXAM 3 - (endocrine)

  1. Corticotropin-releasing hormone (CRH) stimulates secretion of ?
    ACTH
  2. Thyrotopin-releasing hormone (TRH) stimulates secretion of ?
    TSH
  3. growth hormone releasing hormone (GHRH) stimulates secretion of ?
    GH
  4. somatostatin (SST) inhibits secretion of ?
    GH
  5. gonadotropin releasing hormone (GnRH) stimulates secretion of?
    LH and FSH
  6. Dopamine (DA) inhibits secretion of ?
    prolactin
  7. list the major known hypophysiotropic hormones
    • CRH
    • DA
    • TRH
    • SST
    • GHRH

    GnRH
  8. what is inhibitory ?
    • SST INHIBITS GROWTH HORMONES 
    • DA INHIBITS PROLACTIN
  9. what is unique about dopamine ?
    dopamine is a catecholamine and all other hypophysiotropic hormones are peptides
  10. how do the hypophysiotropic hormones reach the anterior pituitary gland ?
    via the hypothalamus- hypophyseal portal vessels
  11. Is long negative feedback possible in the case of prolactin ? Why or why not ?
    NOOO! the breast is an exocrine and not an endocrine gland. it does not participate in a three hormone sequence
  12. prolactin produces what kind of feedback and explain
    SHORT negative feedback, because this hormone acts upon the hypothalamus to stimulate the secretion of dopamine which then inhibits the secretion of prolactin
  13. cortisol negative feedback is what kind
    long loop negative feedback
