16
Q

anterior pitutary

A
  • a pocket of cells
  • neuropeptide hormones enter via cappilaries from posterior pituatary and stimulate/inhibit hormone release
  • produce TROPHIC hormones (control activity of other galnds + hormone release)
17
Q

posterior pituatary

A
  • an extention of hypothalamus
  • part of NS as axons extend down into it
  • produce NEUROPEPTIDE hormones which build up in nerve terminals before release into BS
18
Q

thyroid gland

A
  • butterfly shaped
  • 2 lobes w. thymus connecting anterior to trachea
  • produce LIPID-SOULABLE hormones
19
Q

parathyroid glands

A

4 small islands embedded on posterior of thyroid gland

20
Q

adrenal glands

A
  • located at apex of kidneys

- have inner medulla (hormones affect whole body) and outer cortex (release STEROIDS + LIPID-SOULABLE hormones)

21
Q

pancreas

A
  • exocrine (pancreatic juice into duodeum) + endocrine (hormones of inlets of langerhaus cells)
  • langerhaus cells have 3 types: alpha (producing glucogen), beta (producing insulin), delta (producing somatostatin))
22
Q

what is hyperthyroidism

A

overactive thyroid resulting in too much T3 + T4 production

23
Q

what is hypothyroidism

A

underactive thyroid resulting in not enough T3 + T4 production
