Vedclass · Answer

(A) Prolactin is unique among the anterior pituitary hormones because its secretion is primarily regulated by inhibitory control from the hypothalamus.This inhibitory control is mediated by the neurotransmitter dopamine,which acts as the Prolactin Inhibiting Hormone $(PIH)$.Dopamine is synthesized and released by the tuberoinfundibular neurons in the hypothalamus,which then travels through the hypophyseal portal system to inhibit the lactotrophs in the anterior pituitary.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the Assertion.

$A$: Prolactin is unique among the pituitary hormones as it is under predominant inhibitory control of the hypothalamus.
$R$: The controlling agent is the neurotransmitter dopamine,produced by tuberoinfundibular neurons.
