Hormones Flashcards
(46 cards)
steroid hormones
- nuclear or cytoplasmic receptors
- Binds to DNA
- TF
- cause production of new proteins
examples of steroid hormones
thyroid hormones, cortisol, testosterone, oestrogen/ progesterone
Peptide hormones
cause effect from outside the cell
example of peptide JAK/STAT
GH prolactin
example of peptide Gq
oxytocin, ADH
example of peptide Gs
TSH, ACTH, FSH, LH and ADH
Hypothalamus produces
Somatostatin, dopamine and GnRH
somatostatin
inhibits secretion of GH, including TSH and insulin
dopamine
brain NT which controls movement and involved in regard pathway
GnRH
stimulates release of FSH and LH
A. pituitary
TSH, FSH, LH, GH and prolactin
TSH
stimulates thyroid to release T3 and T4
FSH
maturation of follicles
LH
ovulation and development of CL
GH
stimulates forth, cell generation
Prolactinn
milk production
thyroid produces
T3, T3, cacitronin
calcitronin
controls calcium nd phosphate conc in the blood
-keeps bones strong and helathy
when the hypothalamus senses T3/T4 si low it releases
TRH which causes the a.pituitary to release TSH
t3
regulation of metbaolism- shorter half life and higher metabolic tate
- much lower cones than T4
t4
higher cones, less active
deficiency in iodine leads to
decrease in production of T3/T4
p.pituitary
oxytocin, ADH
oxytocin
NT in the brain.
plays role in social bonding and sexual reproduction
