At about 38 weeks after conception, the fetal brain signals the release of hormones, specifically <u>oxytocin,</u> which prepares the fetus for delivery and begins labor.
Explanation:
Oxytocin is a hormone released by posterior pituitary gland because it is responsible for the uterine contractions during labour.
