Foetal ejection reflex in human female is induced by
A
Differentiation of mammary glands
B
Pressure exerted by amniotic fluid
C
Release of oxytocin from pituitary
D
Fully developed foetus and placenta
Detailed Solution
Parturition is induced by a complex neuroendocrine mechanism.
The signals for parturition originate from the fully developed foetus and the placenta; they induce mild uterine contractions called the foetal ejection reflex.
This reflex then triggers the release of oxytocin from the maternal pituitary, which causes stronger uterine contractions.
So the release of oxytocin is a result of the reflex, not its cause.
Hence the foetal ejection reflex is induced by the fully developed foetus and placenta.
