Endocrine Glands (Anterior Pituitary (Growth Hormone (GH/Somatotropin)…
Endocrine Glands
Anterior Pituitary
-
-
-
-
-
Prolactin (PRL)
promotes milk production in lactating females and other additional actions and also plays a supporting role in the male reproductive system. Inhibited by PIH. - Cyclic AMP second messenger system
-
-
Thyroid
-
Triodothyrine (T3)
One MIT and one DIT+ attached to thyroglobulin and are secreted in the blood and enters the nucleus to stimulate synthesis of mRNA. Also promotes growth and development - Cyclic AMP second messenger system
-
Calcitonin
secreted by parafollicular cells, lowers blood Ca2+ concentrations and antagonize effects of parathyroid. Secreted by C cells which helps the make up of osteoclasts. Cyclic AMP messenger system.
-
Posterior Pituitary
-
Oxytocin
Stimulated by suckling, stimulates contractions of the uterus and mammary gland.
-
Stores and releases from hypthalamo-hypophseal tract both ADH and oxytocin which were produced in the hypothalamus. - Cyclic AMP second messenger system
Adrenal Medulla
Epinephrine
innervated by preganglionic sympathetic axons, uses Phospholipase C/cAMP second messenger system. Activates "fight or flight"
-
Norepinephrine
innervated by preganglionic sympathetic neurons, uses Ca2+ second messenger system. Activates "fight or flight"
-
Pancreas
Glucagon
Stimulated by low blood sugar using alpha cells (glycogenolysis) - uses cyclic AMP second messenger system.
-
Insulin
Stimulated by high blood sugar using beta cells (gluconeogenisis) uses tyrosine kinase 2nd messenger.
-
-
Pineal Gland
Melatonin
superchiasmatic nucleus regulates secretion using sympathetic system, secretion increases with darkness. Used for the circadian rhythm. Cyclic AMP second messenger system.
