Vedclass · Answer

(D) The process of parturition is induced by a complex neuroendocrine mechanism.Signals for parturition originate from the fully developed foetus and the placenta,which induce mild uterine contractions referred to as the foetal ejection reflex.This reflex triggers the release of oxytocin from the maternal pituitary gland,which further stimulates stronger uterine contractions.Therefore,the initial signals originate from both the foetus and the placenta.
