MICROANATOMY

Detailed explanation-1: -Prolactin contributes to hundreds of physiologic functions, but the two primary responsibilities are milk production and the development of mammary glands within breast tissues. Prolactin promotes the growth of mammary alveoli, which are the components of the mammary gland, where the actual production of milk occurs.

Detailed explanation-2: -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-3: -Prolactin (PRL) released from lactotrophs of the anterior pituitary gland in response to the suckling by the offspring is the major hormonal signal responsible for stimulation of milk synthesis in the mammary glands.

Detailed explanation-4: -The main function of Prolactin is to initiate and maintain lactation. It is a lactogenic hormone synthesized by the pituitary gland. Prolactin induces ductal growth, develops the lobular system, and synthesis of milk production. Prolactin is an anterior pituitary hormone for initiating and maintaining lactation.

Detailed explanation-5: -Oestrogen is another key regulator of prolactin and has been shown to increase the production and release of prolactin from the pituitary gland.
