Name the hypothalamic catecholamine that inhibits prolactin

Name the hypothalamic catecholamine that inhibits prolactin synthesis and secretion, and specify 1 region within the hypothalamus that is it is produced. List two catecholamine\'s produced by the adrenals and specify the region within the adrenals that each are produced. List two amine hormones that DO NOT act as neurotransmitters and do not exclusively function via membrane bound receptors

Solution

answer:1)dopamine is the hypothalamic catecholamine that inhibits prolactin synthesis and secretion.

.

REGION:prolactin does not have an endocrine target tissue, and therefore lacks the classical feedback pathway to regulate its secretion. Instead, it is regulated by short loop feedback, whereby prolactin itself acts in the brain to stimulate production of dopamine and thereby inhibit its own secretion.it is secreted in the region of anterior pitutary in the hypothalamus.

2-3)two catecholamines produced by the adrenals are adrenaline and nor adrenaline\'. the adrenal medulla is the region in which the adrenals are produced.

4-5)tryosine and trypotophan.
