Oxytocin is synthesised in

Options

A. Adenohypophysis
B. Neurohypophysis
C. Hypothalamus
D. Epiphysis.

Answer

**Step-by-Step Solution:**

1. **Understanding Oxytocin**: Oxytocin is a hormone that plays a significant role in various physiological functions, including childbirth and lactation.

2. **Identifying the Source of Oxytocin**: The question asks where oxytocin is synthesized. It is important to differentiate between where it is synthesized and where it is released.

3. **Neurohypophysis vs. Hypothalamus**:
- The neurohypophysis (posterior pituitary) is responsible for the storage and release of hormones like oxytocin and vasopressin. However, it does not synthesize these hormones.
- The hypothalamus is the region of the brain that synthesizes oxytocin.

4. **Reviewing Other Options**:
- Adenohypophysis (anterior pituitary) produces different hormones (like growth hormone) and does not synthesize oxytocin.
- Epiphysis (pineal gland) primarily secretes melatonin and is not involved in the synthesis of oxytocin.

5. **Conclusion**: The correct answer is that oxytocin is synthesized in the hypothalamus.

**Final Answer**: Oxytocin is synthesized in the hypothalamus.
