GENERAL HISTOLOGY

Detailed explanation-1: -Prolactin is a polypeptide hormone that is responsible for lactation, breast development, and hundreds of other actions needed to maintain homeostasis. The chemical structures prolactin is similar to the structure of growth hormone and placental lactogen hormone.

Detailed explanation-2: -The brain then signals the hormones, prolactin and oxytocin to be released. Prolactin causes the alveoli to begin making milk. Oxytocin causes muscles around the alveoli to squeeze milk out through the milk ducts.

Detailed explanation-3: -During pregnancy, the hormones prolactin, estrogen and progesterone stimulate breast tissue development and milk production. Prolactin promotes the growth of a certain type of breast tissue called mammary alveoli, which are the components of the mammary gland where the production of milk occurs.

Detailed explanation-4: -Prolactin is a hormone produced by your pituitary gland which sits at the bottom of the brain. Prolactin causes breasts to grow and develop and causes milk to be made after a baby is born. Normally, both men and women have small amounts of prolactin in their blood.

Detailed explanation-5: -The two primary hormones that are needed for lactation are prolactin and oxytocin. Prolactin stimulates milk biosynthesis within the alveolar cells of the breast and oxytocin stimulates contraction of the myoepithelial cells that surround the alveoli, causing the milk to be ejected into the ducts leading to the nipple.
