ANATOMY

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 (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-3: -Dopamine (a brain chemical) and estrogen (a hormone) control prolactin production and release from your pituitary gland. Your central nervous system, immune system, uterus and mammary glands are also capable of producing prolactin.
