Question

Which hormone stimulates the alveoli of the mammary glands to produce milk?

Options

Answer 1

Prolactin is the hormone that stimulates the alveoli to produce milk. Its counterpart, oxytocin, has a different role: it triggers the ejection of the already-produced milk following childbirth.
