The signals for parturtition originate from

Options

(a) placenta only
(b) plascenta as well as fully developed foetus
(c) oxytocin released from materna pituitary
(d) fully devloped foetus only

Correct Answer:

plascenta as well as fully developed foetus

Explanation:

Parturition is the process of delivery of the foetus. The signals for parturition originate from the fully developed foetus and placenta that induce uterine contraction called foetal ejection reflex. This triggers the release of oxytocin hormone from pituitary. This in turn leads to expulsion of the baby out of uterus.
