Cards

Term
adrenal gland
Definition
-on top of kidneys
-adrenal cortex and adrenal medulla
Term
adrenal cortex
Definition
-ACTH stimulates this to produce corticosteroids
Term
glucocorticoids
Definition
-cortisol and cortisone
-raise blood glucose levels and decrease protein synthesis
Term
mineralcorticoids
Definition
-aldersterone
-reabsorption on sodium and water to raise BP
Term
cortical sex hormones
Definition
-androgens-male sex hormones
Term
adrenal medulla
Definition
-epinephrine and norepinephrine
-increases blood glucose levels
-fight or flight response
Term
pituitary gland
Definition
below hypothalmus
Term
anterior pituitary
Definition
regulated by hypothalmus
Term
direct hormones
Definition
stimulate target organs
Term
tropic hormones
Definition
stimulate other endocrine glands to release hormones
Term
growth hormone
Definition
-anterior pituitary
-direct hormone
-stimulates bone/muscle growth
Term
acromegaly
Definition
-too much GH, overgrowth of bone
Term
prolactin
Definition
-anterior pituitary
-direct hormone
-stimulates milk production in mammary glands
Term
ACTH
Definition
-anterior pituitary
-stimulates adrenal cortex to make corticosteroids
Term
TSH
Definition
-anterior pituitary
-stimulates thyroid to release thyroid hormones
Term
LH
Definition
-anterior pituitary
-stimulates ovulation and production of corpus luteum
-regulates progesterone and testosterone
Term
FSH
Definition
stimulates maturation of ovarian follicles that secrete estrogen
-also stimulates maturation of seminiferous tubules and sperm production
Term
Endorphins
Definition
-neurotransmitters that have pain relieving properties
Term
posterior pituitary
Definition
-DOESNT SYNTHESIZE HORMONES
-stores and releases oxytocin and ADH (produced by hypothalmus)
Term
oxytocin
Definition
-posterior pituitary
-uterine contractions and milk secretion
Term
ADH
Definition
-posterior pituitary
-increases permeability of nephron collecting duct
Term
Thyroid hormones
Definition
-iodination of tyrosine
-growth/development of children
-increase rate of metabolism
-thyroxin (t4)
-triiodothyronine (t3)
-calcitonin
Term
calcitonin
Definition
-thyroid hormone
-decreases Ca concentration
Term
pancreas
Definition
-endo and exocrine gland
-islets of Langerhans
-Glucagon and insulin
Term
glucagon
Definition
-pancreas
-produced by alpha cells
-increase blood glucose levels
Term
insulin
Definition
-pancreas
-produced by beta cells
-decreases blood glucose levels
Term
parathyroid
Definition
PTH-raises Ca+ concentration
Term
kidneys
Definition
produce EPO- stimulates RBC production
Term
gastrointestinal hormones
Definition
gastrin, secretin, cholecystokinin
Term
gastrin
Definition
stimulates HCl production
Term
secretin
Definition
stimulates secretion of pancreatic juice
Term
cholecystokinin
Definition
stimulates release of bile
Term
pineal gland
Definition
-tiny structure at base of brain
-melatonin-circadian rhythms
Term
peptide hormones
Definition
neind to receptors and trigger a series of enzymatic reactions (cascade effect)
Term
steroid hormones
Definition
enter target cells directly and bind to specific receptor proteins in the cytoplasm
-this complex enters nucleus and activates expression of genes
Term
auxins
Definition
responsible for phototropism/geotropism
Term
gibberellins
Definition
rapid stem elongation
Term
kinin
Definition
promotes cell division
Term
ethylene
Definition
ripening
