Hypothalamus Hormone
Peptides
Releasing and Inhibiting factors
Targets the anterior pituitary and modifies activity
growth hormone (peptide) is found where
anterior pituitary
what does the growth hormone do
increase bone and muscle growth and increases cell turnover rate
where is prolactin (peptide) found
anterior pituitary gland
what does prolactin do
target = mammary gland
effect =milk production
where is the tropic hormone thyroid stimulating hormone found
anterior pituitary
what does the thyroid stimulating hormone do
target = thyroid effect = synthesis and release of TH
where is the tropic hormone adrenocoricotropic hormone found
anterior pituitary
what does adrenocorticotropic hormone do
increase growth and secretory activity of the adrenal cortex
where is the gonadotropic hormone luteinizing hormone found
anterior pituitary
what does the luteinizing hormone do
target = ovary effect = ovulation
target = testes effect = testosterone synth
where is the gonadotropic hormone follicle stimulating hormone found
anterior pituitary gland
what does the follicle stimulating hormone do
target = ovary effect = follicle development
target = testes effect = spermatogenesis
where is the antidiuretic hormone found
posterior pituitary
what does the antidiuretic hormone do
target = kidney effect = water retention
where is oxytocin found
posterior pituitary
what does oxytocin do
target = breast effect = milk letdown
target = uterus effect = contraction
where is the thyroid hormone found (aka thyroxine)
thyroid
what does the thyroid hormone do
for a child necessary for physical and mental development
for an adult increase metabolic rate and temperature
where is the calcitonin hormone found
in the thyroid C cells
what does calcitonin do
target = bone and kidney effect = lowers serum [Ca2+]
where is the parathyroid hormone found
parathyroid
what does the parathyroid do
target = bone, kidney and small intestine effect = raises serum [Ca2+]
where is the thymosin hormone found
thymus
