MICROANATOMY

Detailed explanation-1: -During labor, when the fetus’s body (usually head) pushes against your cervix, the nerve impulses from this stimulation travel to your brain and stimulate your pituitary gland to release oxytocin into your bloodstream. The oxytocin travels to your uterus and stimulates contractions.

Detailed explanation-2: -Oxytocin both stimulates the muscles of the uterus to contract, and boosts the production of prostaglandins, which also increase uterine contractions. Women whose labor is slow to proceed are sometimes given oxytocin to speed the process.

Detailed explanation-3: -Oxytocin causes contractions in the myoepithelial cells, which increases the pressure in the breast, resulting in a wavelike release of milk from the mammary glands through the lactiferous ducts (5, 13).

Detailed explanation-4: -Oxytocin is an important hormone in labour and birth, when it helps the labouring woman’s uterus to contract and birth her baby.

Detailed explanation-5: -Oxytocin stimulates powerful contractions that help to thin and open (dilate) the cervix, move the baby down and out of the birth canal, push out the placenta, and limit bleeding at the site of the placenta.
