-crine
to secrete or separate
Hormone
greek term meaning “impulse” or “to set in motion”
pituitary gland
located at base of brain just below hypothalamus. AKA hypophysis. Master gland - secretes hormones that control other endocrine glands.
hypothalamus
secretes releasing and inhibiting factors that affect the pituitary gland. produces antidiuretic hormone and oxytocin
infundibulum
funnel-shaped passage connecting the hypothalamus to pituitary gland
adenohypophis
anterior (cranial) lobe of pituitary gland. releases indirect-acting hormones
indirect-acting hormones
cause target organ to produce second hormone
neurohypophis
posterior lobe of pituitary. responds to neurologic stimulus and does not produce hormones, but does store and secrete them.
direct-acting hormones
released by neurohypophis. produce desired effect directly in target organ
thyroid-stimulating hormone
TSH. augments growth and secretions of thyroid gland
adrenocorticotropic hormone
ACTH. augments growth and secretions of adrenal cortex
follicle-stimulating hormone
FSH. augments secretion of estrogen and egg growth in females/sperm in males.
luteinizing hormone
LH. augments ovulation and acids in maintenance of pregnancy.
gonadotropic hormone
FSH and LH included in this category.
interstitial cell-stimulating hormone
ICSH. stimulates testosterone secretion in males.
