Question

Which one of the following hormones stimulates the release of milk from the breast?

a. Prolactin
b. Progesterone
c. hCG (human chorionic gonadotropin)
d. Oxytocin

Answer 1

Oxytocin is the hormone that stimulates the release of milk from the breast.

Step-by-step explanation:

The hormone that stimulates the release of milk from the breast is oxytocin. When the baby begins suckling at the breast, signals are sent to the hypothalamus causing the release of prolactin from the anterior pituitary. Prolactin causes the mammary glands to produce milk, and oxytocin is also released, promoting the release of the milk.
