What is foetal ejection reflex ?

Text Solution

AI Generated Solution

**Step-by-Step Solution:** 1. **Definition of Fetal Ejection Reflex**: The fetal ejection reflex is a physiological process that occurs during childbirth. It is triggered by signals from a fully developed fetus and the placenta. 2. **Source of Signals**: The signals that initiate the fetal ejection reflex come from two main sources: the fully developed fetus and the placenta. These signals indicate that the fetus is ready for birth. 3. **Mechanism of Action**: When the fetus and placenta send these signals, they result in uterine contractions. These contractions are the body's way of responding to the signals, indicating that it is time for the baby to be expelled. ...
