Question

Foetal ejection reflex in human female is induced by

• A. Placenta only.
• B. Fully developed foetus and placenta.
• C. Release of oxytocin from the pituitary gland.
• D. Release of full developed corpus luteum.

Answer 1

The correct option is B Fully developed foetus and placenta.

Vigorous contraction of the uterus at the end of pregnancy causes expulsion/delivery of the foetus (parturition). Parturition originates from the fully developed foetus and the placenta which induces mild uterine contractions called foetal-ejection reflex.
