Somatostatin is produced by

Options

A. Adenohypophysis
B. Neurohypophysis
C. Pineal gland
D. Basal part of diencephalon.

Answer

**Step-by-Step Solution:**

1. **Understanding Somatostatin**: Somatostatin is a hormone that is known for its role in inhibiting growth hormone release. It is often referred to as a growth-inhibiting hormone.

2. **Identifying the Source**: The question asks where somatostatin is produced. It is important to know the anatomical origin of the hormone.

3. **Reviewing the Options**: The options provided are:
- A) Adenohypophysis
- B) Neurohypophysis
- C) Pineal gland
- D) Basal part of the diencephalon

4. **Analyzing Each Option**:
- **Adenohypophysis**: This is the anterior part of the pituitary gland, which produces several hormones but not somatostatin.
- **Neurohypophysis**: This is the posterior part of the pituitary gland, which stores and releases hormones produced by the hypothalamus, but does not produce somatostatin itself.
- **Pineal Gland**: This gland primarily produces melatonin and is not involved in the production of somatostatin.
- **Basal Part of the Diencephalon**: The hypothalamus, which is located in the diencephalon, is responsible for the production of somatostatin.

5. **Conclusion**: Based on the analysis, the correct answer is that somatostatin is produced by the basal part of the diencephalon, specifically the hypothalamus.

**Final Answer**: Somatostatin is produced by the basal part of the diencephalon (hypothalamus).
