Endocrine System
Term | Definition |
---|---|
Hypothalamus | Coordinates the autonomic nervous system and the activity of the pituitary controlling body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity. |
Pituitary | Controls growth and development and the functioning of the other endocrine glands |
Pineal Gland | A pea-sized conical mass of tissue behind the third ventricle of the brain, secreting a hormone like substance |
TH/Thyroid Gland | Secretes hormones regulating growth and development through the rate of metabolism. |
PTH/Parathyroid Gland | Produce parathyroid hormone |
Adrenal Gland | Produces glucocorticoid, mineralocorticoid, and androgenic hormones and an ectodermal medulla that produces epinephrine and norepinephrine |
Oxytocin | Causes increased contraction of the uterus during labor and stimulates the ejection of milk into the ducts of the breasts. |
Mineralocorticoids | Aldosterone (sodium retention) involved with maintaining the salt balance in the body. |
Glucocorticoids | Cortisol (metabolism, ant-inflammatory) |
Gonadocorticoids | Sex hormones |
Pancreas | Secretes digestive enzymes into the duodenum |
Alpha cells/Glucagon | The breakdown of glycogen to glucose in the liver. |
Beta cells/Insulin | Regulates the amount of glucose in the blood |
hCG/Chronic Gonadotropin | Maintain corpus luteum function. |
Estrogen | Promote the development and maintenance of female characteristics of the body. |
Progesterone | Released by the corpus luteum that stimulates the uterus to prepare for pregnancy. |
Testosterone | Stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex. |
Gastrin | Stimulates HCI release |
Secretin | Stimulates liver and pancreas. |
Cholecystokinin | Sphincters of pancreas & gallbladder. |
Serotonin | Constricts the blood vessels and acts as a neurotransmitter. |
Leptin | Appetite control |
Resistin | Insulin antagonist |
Adiponectin | Enhances sensitivity to Insulin |
ANP/Atrial Natriuretic Peptide | Decreases Na+ |
EPO/Erythropoietin | RBC production |
Renin | Renin-angiotensin-aldosterone mechanism (increases BP) |
Osteocalcin | Insulin secretion, reduces body fat, improves glucose metabolism. |
Cholecalciferol | Vitamin D precursor |
Thymus | T lymphocyte's mature. |
Thymulin | T cell development non-apeptide. |
Thymopoietins | T cell development involved in the induction of CD90 in the thymus. |
Thymosins | T cell development hormone of the thymus, and it stimulates the development of disease-fighting T cells . |
Catecholamine's | Epinephrine, Norepinephrine, & Dopamine. |
