Title: What hypothalamic control mechanisms are used to affect endocrine activity in the anterior pituitary? Post by: lexus3431 on Aug 17, 2013 The hypothalamus controls the anterior pituitary through a series of releasing hormones
Releasing hormones travel in a portal system to the pituitary gland They either stimulate of inhibit the release of anterior pituitary hormones The anterior pituitary produces 6 major hormones ACTH - acts on the adrenal cortex TSH - acts on the thyroid LH / FSH act on the ovaries and testes Prolactin - acts on the breast Growth hormones - has diverse actions The anterior pituitary is controlled by negative feed back loops Title: What hypothalamic control mechanisms are used to affect endocrine activity in the anterior pituitary? Post by: LIM1812 on Aug 17, 2013 hypothalamus secrete many hormones that affect the action of adenohypophysis(ant. pituitary)
there are both releasing and inhibiting hormones for both growth h. and prolactin h. while there are only releasing h. for : TSH,FSH,LH,ACTH allthese hormones are released from axonal ends of hypothalamic neurons and find their way to the ant. pit. via portal system of circulation |
