Endocrine System Flashcards
Endocrine Glands
Secrete hormones into body fluids
Exocrine Glands
Secrete substances into outside environment
Tropic Hormones
Hormones that act on other glands to regulate their hormone secretion
Nervous System Control
Directly stimulates some glands to secrete their hormones via nerve impulses
Changes in Composition of Internal Environment
Changing levels of a specific substance in the blood stimulates or inhibits secretion of certain hormones
Prostaglandin (Group of Lipids)
Hormone-like messengers in the body
Alpha Cells
Releases glucagon
Beta Cells
Releases insulin
Delta Cells
Releases somatostatin (a regulatory hormone that inhibits the release of various hormones)
Pineal Gland
Releases melatonin
Thymus Gland
Releases thymosin
Pancreas
Releases insulin and glucagon
Adrenal Gland
Releases cortisol, aldosterone, and adrenaline
Parathyroid Gland
Releases parathyroid hormone
Thyroid Gland
Releases thyroid hormones and calcitonin
Pituitary Gland
Releases growth hormone, prolactin, and ACTH (a hormone that stimulates the adrenal cortex to produce cortisol)
Hypothalamus
Releases dopamine and CRH (a hormone that stimulates the pituitary gland to release ACTH to produce cortisol)
