Vedclass · Answer

(C) The signal for parturition originates from the fully developed foetus and the placenta,which induce mild uterine contractions called the foetal ejection reflex.This reflex triggers the release of $ACTH$ (Adrenocorticotropic hormone) from the pituitary gland of the foetus.This $ACTH$ stimulates the adrenal glands of the foetus to release corticosteroids.These signals eventually trigger the release of $Oxytocin$ from the mother's posterior pituitary gland,which acts on the uterine muscle to cause vigorous uterine contractions.
