Oxytocine is essential for which one of the following actions

Options

A. Fertilization of ova
B. Synthesis of estrogens
C. Synthesis of milk
D. Ejection of milk

Answer

**Step-by-Step Solution:**

1. **Identify the hormone in question**: The question asks about oxytocin, which is a hormone produced by the posterior pituitary gland.

2. **Understand the functions of oxytocin**: Oxytocin is known for its role in stimulating contractions of smooth muscles, particularly during childbirth (parturition) and in the ejection of milk during breastfeeding.

3. **Evaluate the options provided**:
- **Fertilization of ova**: Oxytocin does not play a role in fertilization.
- **Synthesis of estrogen**: Oxytocin is not involved in the synthesis of estrogen.
- **Synthesis of milk**: The hormone responsible for milk synthesis is prolactin, not oxytocin.
- **Ejection of milk**: Oxytocin is crucial for the ejection of milk from the mammary glands during breastfeeding.

4. **Select the correct answer**: Based on the functions of oxytocin, the correct answer is the ejection of milk.

**Final Answer**: Oxytocin is essential for the ejection of milk.
