The foetal ejection reflex in humans triggers release of
Options
(a) Oxytocin from maternal pituitary
(b) Oxytocin from foetal pituitary
(c) Human Choronic Gonadotropin (hCG) from placenta
(d) Human Placental Lctogen (hPL) from placenta
Correct Answer:
Oxytocin from maternal pituitary
Explanation:
Parturition is induced by a complex neuroendocrine mechanism. 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.
