Endocrine agans - How Hurmones workHypothalamus1. Releasing / inhibitory Hormones1.causes Antidiveretic Hormone (ADH)Posterior Pituitary GlandHypothalamuscontrols thestimulates Pitultary glandpituitaryand its hormonesavandmore kidneys towater (T BP) reabsorb Urine varmelPineal GlandmelatoninAnterior Pituitary Gland2. Oxytocinregulates sleeplwake cycleAdrencorticotropic hormone (ACTH)- stimulates contraction of uterus-causes Adrenal gland to release sieroidand labor mammary glands duringhormones-2. Follicle stimulating Hormone (FSH)causes mammary glands to release milkstimulates production of ova spermParathyroid Gland3. Lutenizing Hormone (LH)Thyroid Gland1. Parathyroid H. (PTH)stimulates ovaries & testesstimulates release1. Triiodothyronine (T3)of calcium from4. Thyroid-srmvlating Hormone (TSH)- -metabolismBones- stimulates thyroid glandBlood calcium2. Thyroxine (T4)5. Growth Hormone (GH)levels- metabolism and temperature- causes cells to grow and repair- Iodine is an essential element6. prolactin (PRL)3. calcitonin-inhibits release of calcium from BonesGreatcauses mammary glands to produce milk- V Blood calcium levels7. Endorphins- inhibits painThymusHEARTAdrenal cortex1. Thymos ine1. Aldosterone- stimulates T-cell development- Requested sodium in the bloud- Trains lymphocites to- increase BP. urine volumerecognize pathogens +2. cortisolignore environment- -manages stress responsekidneys- increase Blood GlucosePancreas1. Erythropoletin- Decreases inflammation1. Insulin-Response to cellular hypoxiaAdrenal medulla- storage hormone2. Reninpromotes production of- causes blood glucose levelsAngiotensin1. Epinepherine- Fight- Produced by the islets of langehansto decrease2. Novepinepherine2. Glucagon-Flight- increases blood glucoseovaries (steroid hormones)OR1. Estrogen- stimulates egg maturationTestes (steroid hormone)- Develop secondary sex characteristics2 Progesterone1. Testosterone- Regulates sperm production- prepares uterus to recieve fertilized egg- maintains the uterive wall- Develops secondary sex characteristicsEndocrine Glands (In order)HypothalamusPineal GlandPitultary GlandParathyroid Glands Thyroid GlandsThymusLiverAdrenal GlandkidneypanareasOvary, Testes QUICK!
