Artis Amerika Hot Physiology of Lactation: Two factors are regulated by hormones involved in lactation physiology. (1.) Production. In the physiology of lactation, prolactin, a hormone secreted by the breast milk of anterior pituitary gland, it is important for the production of breast milk, (prolactin) but although the levels of this hormone in the maternal circulation increases during pregnancy, the hormones are inhibited by placental hormones. With the release or discharge of the placenta at the end of the delivery process, the estrogen and progesterone levels gradually decreased until the level of prolactin to the release and reactivation. An increasing blood supply circulating through the breast and can be extracted essential ingredient for the formation of milk.

Globulin, fat and protein molecules from the bottom of the secretory cells will swell the acini and pushed toward the tubule laktifer. Increased levels of prolactin will inhibit ovulation and thus also has the function of contraception, but she needs to give breast milk 2 to 3 times every hour to take effect is really effective. Prolactin levels are highest at night, and Cessation of breast milk first performed at night, which usually is so, then the methods of contraception is more rel label should be used when wanting to avoid pregnancy.

(2.) Expenditure milk (oxytocin). a. The pressure from behind. b. Neurohormonal reflex. Two factors are involved in the milk flow from secretory cells into the mammary papilla. Pressure globuli newly formed within the cell will push into the tubule globuli laktifer and sucking by the baby will stimulate more milk secretion. If the baby is breastfed, then suck the rhythmic movements would produce nerve impulses contained in the posterior pituitary gland. A direct result of this reflex is the release of oxytocin from the posterior pituitary: this will cause mioepitel cells (cells' basket 'or spider cells') around the alveoli to contract and push milk into the lactifer vessels, and thus more much milk that flows into the ampullae. This reflex can be inhibited by the presence of pain, such as stitches perineum. Thus it is important to place the mother in a comfortable position, relaxed and free and pain, especially during the hours the child lactation. The same oxytocin secretion will cause the uterine muscles to contract and help the involution of the uterus during puerperium (days post partum).
