GENERAL HISTOLOGY

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 in the circulation stimulates uterine contractions and oxytocin released within the brain influences maternal physiology and behaviour during birth.

Detailed explanation-3: -The two main actions of oxytocin in the body are contraction of the womb (uterus) during childbirth and lactation. Oxytocin stimulates the uterine muscles to contract and also increases production of prostaglandins, which increase the contractions further.

Detailed explanation-4: -OXYTOCIN: NORMAL PHYSIOLOGY Oxytocin is a powerful reproductive hormone with widespread effects on the brain and body of all mammals, for example, by mediating sperm ejection, labor contractions, and milk ejection.

Detailed explanation-5: -Some studies have found that oxytocin levels increase at the onset of labor and during labor compared to 1 or 2 weeks before labor (9), reaching a peak just when the head of the baby is delivered (10).
