| 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. |
