define GLAND
group of specialized epithelial cells producing secretions
define EXOCRINE GLANDS & give examples
secrete hormones into ducts (ex: salivary, mmmary, sweat)
define HORMONES
chemical messengers from endocrine glands that affect almost every organ & cell
describe ENDOCRINE GLANDS
don’t have ducts so release hormones into blood streams; 13 glands of this type
describe PITUITARY GLANDS
pea-sized gland that hangs below hypothalamus that control activity of other endocrine gland & responds to stimuli from neurohormones secreted by hypo...
define ADRENOCORTICOTROPIC HORMONE (ACTH)
hormone of anterior pituitary that controls cortisol production

define THYROID-STIMULATING HORMONE (TSH) | hormone of anterior pituitary that stimulate & regulate thyroid function |
describe ANTIDIURETIC HORMONE (ADH) | hormone of posterior pituitary secreted by hypothalamus & stored in pituitary, lower water excretion thru kidneys leading to blood pressure & constricts blood vessels |
define OXYTOCIN (OXT) | hormone of posterior pituitary that control birth contractions, controls postnatal hemorrhage, & stimulate milk release |

list hormones of pituitary | adrenocorticotropic hormone; follicle-stimulating hormone; growth hormone; lactogenic hormone; luteinizing hormone; melanocyte-stimulating hormone; thyroid-stimulating hormone; antidiuretic hormone; oxytocin |
describe THYROXINE (T4) | hormone of thyroid; controls metabolism & temperature |
describe TRIIODOTHYRONINE (T3) | hormone of thyroid; control metabolism & temperature & is more powerful than T4; rate of secretion controlled by TSH |
describe CALCITONIN | hormone of thyroid; works w/parathyroid hormone that lowers calcium in blood/tissue by moving into bone |
list hormones of thyroid | thyroxine, triiodothyronine, calcitonin |
define PARATHYROID GLANDS | size of grain of rice in posterior surface of thyroid gland |
