Glands ,Hormones,Functions And Structure



LH=lutenizing hormone  FSH=follicle stimulating Hormone     ADH=Antidiuretic hormone


GLANDS HORMONE FUNCTION STRUCTURE
Hypothylamus thyrotripin releasing hormone stimulate secretion of TSH & PROLECTIN peptide

corticotropin R.H cause release of ACTH


GHRH cause release of GH


GHIH inhibit released GH


gonado tropin RH cause release of LH & FSH


dopamin inhibitroy factor inhibit release of protecting H Amine
Interior pitutary G.H stimulate protine synthesis & overall G of most cells and tissues peptide

TSH stimulate synthesis & secretion of thyriod H


ACTH stimulate synthesis & secretion of A corticle H


Prolectin promotes development of the female brest & milk


FSH cause G of folicle in ovary and sperm maturation


LH S. testesteron syn.in lading cell in testies.formation of CL.Stim.ovalation.estrogen & progesteron synthesis in ovary.

Posterior pitutary ADH increase water reabsoption by the kidney and vaso constriction & increase B.P


Oxycitocin S. milk ejectiot trom teats and utrine contraction

Thyroid thyroxinT4 & tri idothyanin T3 increase rate of chem.reaction in most cell thus increase matabolic rate Amine

calcitonin promotes decomposition of Ca in bones & decrease Ca in extra cellular fluid peptide
Adrenal cortex corticoid hm Styriod

aldosteron increase Na reabsorption,incre K secretion & H secretion

Adrenal medulla epineprin & norepinephrin increase the activity of parasynthetic NS Amine
Pancreas insuline from B cells promotes glucose entry in many cells. Controle metabolism of CHO peptide

glucagon in A cells increase syn. & release of glucose from liver into body

Parathyroid thyroid H serumCa conc. By increase absorption by the gut and kidney & release Ca in bone

Testies testestiron promote D of MRS & sexsuall characteristics

Ovary estrogen primote G & D of FRS,F brest and sexsual chara.

placenta HCG priomotes G of CL & release estrogen & progesteron
