Question

Write a paragraph on the prolactin Hormome (PRL).

Using the following passway:

Hypothalamus—> PIH—> blood —> Anterior pituitary—> PRL—> blood —> mammatory gland

Answer 1

Prolactin harmone is also called luteotropic organ that is a protein which has best role in production of milk usually in females

prolactin is secreted from pituitary which is regulated by the endocrine neurons in the Hypothalamus

The neurons of anterior pituitary secrete prolactin inhibiting harmone (aka dopamine) causing inhibition of prolactin harmone

There is stimuli for prolactin secretion is suckling,the effect of which neuronally mediated passes through Blood

It causes stimulation of anterior pituitary to secrete Prolactin releasing harmone(PRL) which is controlled by pit-1 transcription factor that binds to prolactin gene which cause the release of prolactin

Then the stimulus which is generated by suckling of baby the prolactin passes through blood and reaches the mammatory gland by which infant suckles the milk
