The milk ejection reflex requires the action of the hormone ___________.

Question

Quizplus · Accepted Answer

The milk ejection reflex, also known as let-down, is triggered by the hormone oxytocin. Oxytocin is released by the pituitary gland in response to suckling or pumping of the breast. This hormone causes the contraction of smooth muscles around the milk ducts, forcing milk to be released out of the nipples. Prolactin, estradiol, and somatomammotropin are all involved in milk production, but not specifically in the milk ejection reflex.
