Question

Quizplus · Accepted Answer

Prolactin is primarily responsible for the stimulation and maintenance of milk production in the mammary gland, but it is not the primary hormone involved in the milk let-down reflex. Oxytocin, which is also secreted by the anterior pituitary gland, plays a more significant role in the milk let-down reflex by causing the contraction of smooth muscle cells in the mammary gland ducts, leading to the release of milk.
