Vedclass · Answer

(D) The correct answer is $D$. Parturition is induced by a complex neuroendocrine mechanism. The signals for parturition originate from the fully developed foetus and the placenta,which induce mild uterine contractions known as the foetal ejection reflex. This reflex triggers the release of oxytocin from the maternal pituitary gland. Oxytocin acts on the uterine muscles and causes stronger uterine contractions,which in turn stimulates further secretion of oxytocin. The stimulatory reflex between the uterine contraction and oxytocin secretion continues,resulting in stronger and stronger contractions. This leads to the expulsion of the baby out of the uterus through the birth canal.
