Which of the following hormones play a role in the release of milk from mammary glands?

Explanation

Oxytocin has two target tissues—the uterus and the mammary glands in females. After childbirth, this hormone helps the uterus return to its normal condition, and during lactation it contracts the myoepithelial cells of the mammary gland and increases milk ejection. Milk producers also give injections of artificial oxytocin to obtain more milk from cows and buffaloes; this injection/medicine is called Pitocin.
