Foetal ejection reflex in human female is induced by:

Options

A. Release of hormones from placenta
B. Growth and development of ovarian follicles
C. release of oxytocin from material pituitary
D. Release of gonadotrophine

Answer

**Step-by-Step Solution:**

1. **Understanding the Fetal Ejection Reflex**: The fetal ejection reflex is a physiological response that occurs during childbirth. It is a complex neuroendocrine mechanism that is crucial for the process of parturition (the act of giving birth).

2. **Role of the Fetus and Placenta**: The reflex is initiated by signals originating from a fully developed fetus and the placenta. These signals are essential for triggering the process of labor.

3. **Hormonal Influence**: The question specifically asks about what induces the fetal ejection reflex. Among the options provided, we need to identify the key hormonal factor involved.

4. **Oxytocin's Role**: The release of oxytocin from the maternal pituitary gland is a critical component of this reflex. Oxytocin is a hormone that stimulates uterine contractions.

5. **Mechanism of Action**: Once released, oxytocin acts on the uterine muscles, causing them to contract. These contractions become progressively stronger, leading to the expulsion of the baby and the placenta through the birth canal.

6. **Conclusion**: Based on the information analyzed, the correct answer to the question is option c: "Release of oxytocin from maternal pituitary."

**Final Answer**: c. Release of oxytocin from maternal pituitary.
