Vedclass · Answer

(A) The process of parturition (childbirth) is induced by a complex neuroendocrine mechanism.$1$. The signals for parturition originate from the fully developed fetus and the placenta,which induce mild uterine contractions called the fetal ejection reflex.$2$. This fetal ejection reflex triggers the release of oxytocin from the maternal pituitary gland.$3$. Oxytocin acts on the uterine muscle and causes stronger uterine contractions,which in turn stimulates further secretion of oxytocin.$4$. This stimulatory reflex between the uterine contraction and oxytocin secretion continues,resulting in stronger and stronger contractions,eventually leading to the expulsion of the baby out of the uterus through the birth canal.

The signals for parturition originate from the fully developed fetus and the placenta,which induce mild uterine contractions called the fetal ejection reflex. This triggers the release of which hormone?
