Anterior lobe<br><br><ul><li>except prolactin .. anterior lobe stimulate the production of hormones by a peripheral endocrine gland or the liver .

Hypothalamic factors control release of antrrior lobe </li></ul>

posterior lobe<br><br><ul><li>Hormones in posterior are storaged only. secreted from hypothalamus and storaged in posterior lobe. posterior lobe hormones stimiulate directly </li></ul>

GH,ACTH,MSH,TSH,FSH,LH,PROLACTIN

GH:growth of bones and muscles and anti insulin activity<br><br><ul><li>1.stimulate growth of bones and muscles

2.dec carbs metabolism

3-promots protein and fat metabolism </li></ul>

ACTH: inc. adreno cortical hormone<br><br><ul><li>inc synthesis and realese</li></ul>

GHRH (+) .. Somatostatin(-)

MSH: Melanocytes

CRH

TSH: inc thyroid hormones :T3 & T4

FSH: stimulate female follicle and male sperm

TRH:thyroid releasing hormone

LH: ovulation and increase progestrone and estrogen and male testosterone

GnRH<br><br><ul><li>Estrogen

progesterone

testosterone</li></ul>

prolactin: stimulate milk production

Dopamine inhibts prolactin<br><br><ul><li>hyper lactinimeia:

1-lactotrophic secreting cells

give dopamine agonist

2.drug induced by dopamine antagonist</li></ul>

OXYTOCIN, ADH

ADH: decrease diuresis by NA & water reabsorption by kidney

Oxytocin: contract pregnant uterus and milk production
