Supra optic nuclei (in hypothalamus) secrete the hormone

Options

A. ADH
B. Oxytocin
C. Pitocin
D. Both (2) & (3)

Answer

**Step-by-Step Solution:**

1. **Understanding the Location**: The supraoptic nuclei are located in the hypothalamus, which is situated above the pituitary gland in the brain.

2. **Identifying the Function**: The primary function of the supraoptic nuclei is to produce hormones.

3. **Hormones Secreted**: The two main hormones secreted by the supraoptic nuclei are:
- **Antidiuretic Hormone (ADH)**: Also known as vasopressin, it helps regulate water balance in the body and can affect blood pressure.
- **Oxytocin**: This hormone is involved in various functions including childbirth and lactation.

4. **Storage and Release**: Although these hormones are produced in the hypothalamus, they are stored and released from the posterior lobe of the pituitary gland.

5. **Conclusion**: Therefore, the correct answer to the question is that the supraoptic nuclei secrete both ADH and oxytocin.

**Final Answer**: The supraoptic nuclei in the hypothalamus secrete both ADH (antidiuretic hormone) and oxytocin.
