Vedclass · Answer

(A) Parturition is induced by a complex neuroendocrine mechanism. $1$. The signals for parturition originate from the fully developed foetus and the placenta which induce mild uterine contractions called Foetal Ejection Reflex. $2$. This 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 $Oxytocin$. $4$. The stimulatory reflex between the uterine contraction and $Oxytocin$ secretion continues,resulting in stronger and stronger contractions,leading to the expulsion of the baby out of the uterus through the birth canal.
