Q. Foetal ejection reflex in human female is induced by:
A) release of oxytocin from pituitary
B) fully developed foetus and placenta
C) differentiation of mammary glands
D) pressure exerted by amniotic fluid
Explanation
[Solution from source] NCERT states that the signals for parturition originate from the fully developed foetus and the placenta, which induce mild uterine contractions called the foetal ejection reflex. This reflex then triggers oxytocin release, so oxytocin is a result, not the initial inducer. Answer (2).
