The process of lactation


The process of lactation 

is the biological term used for the production of breast milk. When a baby suckles at the breast, nerve impulses are sent from the special receptor cells located in the breast of the hypothalamus, which is located in the brain. The hypothalamus is stimulated to activate when the pituitary gland produces two hormones Ninto different

Lactation





These hormones called oxytocin and prolactin. The hormone oxytocin is stored in the pituitary and acts on muscle cells.
 These muscles surrounding the mammary glands where milk is produced. Oxytocin causes muscle cells to contract in turn, squeezing the milk glands in the ducts.


v  Prolactin is the hormone that is second involved in the process of lactation. Prolactin is also produced by the pituitary gland and is released into the bloodstream whenever the baby suckles at the breast. When prolactin is released into the bloodstream, it moves to the mammary glands in the chest and stimulates the glands to produce milk.
 Level increases prolactin in the mother during pregnancy, but milk production is suppressed by another hormone, progesterone, until the level decreases after birth.

Oxytocin causes what is known and designated as the "drop" of milk glands.

 This causes different sensations of different mothers.
 Some will bring pains, others report a tingling sensation and sensation. Some report no sensation at all. Everything is normal. After this process, the milk is then transferred to the baby through breast a combination of two processes:

* Active expulsion of milk by the mother due to let down reflex

* Remove active child who works on breast tissue with the tongue and jaw to receive the milk.

More a baby suckles in the more milk will be produced. The mother should take the baby to the breast frequently so that her milk can follow demands of the growing baby.
