Q11. What is foetal ejection reflex? How it helps in parturition?


The signals for parturition originate from the fully developed foetus and the placenta which induce mild uterine contractions called foetal ejection reflex.
This triggers release of oxytocin from the maternal pituitary. Oxytocin acts on the uterine muscle and causes stronger uterine contractions. This leads to expulsion of the baby out of the uterus through the birth canal – parturition.
