Hypothalamus contains several group of neurosecretory cells called

Options

A. Tract
B. Pituitary gland
C. Nuclei
D. protoplasm

Answer

**Step-by-Step Solution:**

1. **Understanding the Hypothalamus**: The hypothalamus is a crucial part of the brain that plays a significant role in hormone regulation and homeostasis.

2. **Identifying Neurosecretory Cells**: The question asks for the specific groups of neurosecretory cells located in the hypothalamus. Neurosecretory cells are specialized neurons that release hormones into the blood.

3. **Evaluating Options**:
- **Tract**: This refers to a bundle of nerve fibers and does not represent neurosecretory cells. It connects the hypothalamus to other brain regions.
- **Pituitary Gland**: While the hypothalamus is connected to the pituitary gland, the gland itself is not a group of neurosecretory cells.
- **Nuclei**: This term refers to groups of neuron cell bodies in the central nervous system. In the context of the hypothalamus, certain nuclei are indeed composed of neurosecretory cells.
- **Protoplasm**: This is a term for the living substance within a cell and does not refer to any specific group of cells.

4. **Conclusion**: The correct answer is "nuclei" as they represent the groups of neurosecretory cells found in the hypothalamus.

**Final Answer**: Nuclei
