Hormone summary
STUDY
PLAY
TRH
Stimulate TSH from anterior pituitary. Stimulate PRL from anterior pituitary.
GHRH
Stimulate GH from anterior pituitary.
GnRH
Stimulate FSH from anterior pituitary. Stimulate LH from anterior pituitary.
CRH
Stimulate ACTH from anterior pituitary.
OT
Uterine contractions, lactation
ADH
Promote water re-absorption and increasing blood volume
Melatonin
Antioxidant, monitor the circadian rhythm
GH
Stimulate growth and cell reproduction. Stimulate IGF1 from liver
TSH
Stimulate T3 and T4 synthesis and from thyroid. Stimulate iodine absorption
ACTH
Stimulate corticosteroid and androgen from adrenocortical cells
FSH
In Female: Stimulate maturation of ovarian follicles
In Male: Stimulate maturation of seminiferous tubules, spermatogenesis, and production of androgen-binding protein from testes
LH
In Female: Stimulate ovulation, formation of corpus luteum
In Male: Stimulate testosterone synthesis from testes
PRL
Stimulate milk synthesis
MSH
Stimulate melanin synthesis and release from skin/hair melanocytes
OT
Uterine contraction, lactation
ADH
Promotes water re-absorption and increases blood volume
T3
Increase metabolic rate and protein synthesis
T4
Increase metabolic rate and protein synthesis
Calcitonin
Reduces blood Ca2+
PTH
Regulates Ca2+, Mg2+, and HPO4 2-
Insulin
Intake glucose, glycogenesis and glysolysis in liver and muscle from blood, intake of lipid and synthesis of TG in adipocytes
Glucagon
Glycgenolysis and gluconeogenesis in liver, increase blood glucose level
Somatostatin
Inhibit release of insulin and glucagon
Pancreatic polypeptide
Inhibit somatostatin secretion and pancreas secretion activities
Glucocorticoids
Stimulate gluconeogenesis, fat breakdown, inhibit protein synthesis, glucose uptake in muscles and adipose tissue, immunosuppressive, anti-inflammatory
Mineralocorticoids
Stimulate active Na+ and water re-absorption in kidney, thus increase blood volume and pressure. Stimulate K+ and H+ secretion into kidney and subsequent excretion
Androgens
In Female: Promote libido, converted to estrogen
In Male: Small amount
Epinephrine
Fight-or-flight response
Norepinephrine
Fight-or-flight response
Testosterone
Regulates production of sperm
Progesterone
Support pregnancy
Estrogen
Regulate menstrual cycle, prepare for lactation
What hormones are produced by thymus cell and what is their effect?
Thymosin, thymic humoral factor, thymic factor and thymopoietin. Effect: Promote maturation of T cells
