Foetal ejection reflex is produced by

Options

A. Well developed foetus
B. Placenta
C. Undeveloped foetus
D. Both (A) & (B)

Answer

To solve the question regarding what produces the fetal ejection reflex, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Fetal Ejection Reflex**:
- The fetal ejection reflex is a physiological response that occurs during childbirth. It involves a series of uterine contractions that help in the delivery of the baby.

2. **Role of the Fetus and Placenta**:
- The reflex is initiated by signals from the fully developed fetus and the placenta. The presence of a mature fetus signals the body that it is time for delivery.

3. **Mechanism of Action**:
- As the fetus develops and gets ready for birth, it exerts pressure on the cervix. This pressure is detected by stretch receptors, which send signals to the brain.

4. **Release of Oxytocin**:
- The brain responds by stimulating the release of oxytocin from the maternal pituitary gland. Oxytocin is a hormone that causes the uterus to contract more forcefully.

5. **Uterine Contractions**:
- The increased levels of oxytocin lead to stronger and more frequent uterine contractions, which help push the baby through the birth canal during parturition.

6. **Conclusion**:
- Therefore, the fetal ejection reflex is produced by the combination of the fully developed fetus and the placenta.

### Final Answer:
The fetal ejection reflex is produced by the fully developed fetus and the placenta.
