Which one of the following part also responsible for secretion of hormones in neural system ?

Options

A. Cerebral cortex
B. Cerebellum
C. Hypothalamus
D. Optic lobes

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks which part of the nervous system is also responsible for the secretion of hormones. This indicates that we need to identify a part of the brain that has dual functions: neural activity and hormone secretion.

2. **Reviewing the Options**: The options provided are:
- Cerebral cortex
- Cerebellum
- Hypothalamus
- Optic lobes

3. **Analyzing Each Option**:
- **Cerebral Cortex**: Primarily involved in higher brain functions such as thought, memory, and voluntary muscle movements. It does not play a direct role in hormone secretion.
- **Cerebellum**: Responsible for coordination and balance. It does not have a role in hormone secretion.
- **Hypothalamus**: Located in the lower central part of the brain, it serves as a critical link between the nervous system and the endocrine system. It produces hormones that control the release of hormones from the pituitary gland.
- **Optic Lobes**: Primarily involved in processing visual information. They do not secrete hormones.

4. **Identifying the Correct Answer**: Based on the analysis, the hypothalamus is the only part that links the nervous system and the endocrine system and is responsible for hormone secretion. Therefore, the correct answer is the **Hypothalamus**.

5. **Conclusion**: The hypothalamus is the part of the brain that is responsible for the secretion of hormones in the neural system.

### Final Answer:
The correct answer is **Hypothalamus**.
