Question

Signals for parturition originate from ___________.

• A. fully developed foetus only
• B. GnRH released from maternal hypothalamus
• C. placenta only
• D. both placenta as well as fully developed foetus

Answer 1

The correct option is D both placenta as well as fully developed foetus

Parturition is the process of delivery of foetus. It is the act of expelling the full term young one from the mother’s uterus at the end of gestation period. The signals for parturition originate from the fully developed foetus and the placenta which induce uterine contractions called foetal ejection reflex. GnRH stimulates the pituitary to release gonadotropins.
