ANATOMY

Detailed explanation-1: -Prolactin. Prolactin is necessary for the secretion of milk by the cells of the alveoli. The level of prolactin in the blood increases markedly during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk (19).

Detailed explanation-2: -Prolactin is a polypeptide hormone that is responsible for lactation, breast development, and hundreds of other actions needed to maintain homeostasis.

Detailed explanation-3: -Prolactin (also known as lactotropin and PRL) is a hormone that’s responsible for lactation, certain breast tissue development and contributes to hundreds of other bodily processes.

Detailed explanation-4: -Prolactin levels decrease as lactation is established but nursing stimulates prolactin release from the pituitary which promotes continued milk production. Prolactin is secreted into milk at levels representative of the average circulating concentration.

Detailed explanation-5: -Prolactin is a polypeptide hormone produced by pituitary lactotroph cells. It is also produced locally in a variety of extrapituitary tissues such as mammary glands, decidua, gonads, brain, liver, fat, pancreas, and the immune system, along with its receptors. Prolactin is highly pleiotropic in terms of its functions.
