Secondary egg membrane of human is formed by:-

Options

A. Mucopolysaccaride
B. Granulosa cells
C. mucaus cell
D. Thecal cell

Answer

To answer the question regarding the formation of the secondary egg membrane in humans, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding the Secondary Egg Membrane**:
- The secondary egg membrane in humans is also known as the granulosa cell layer. It plays a crucial role in protecting the developing egg (oocyte).

2. **Role of Granulosa Cells**:
- Granulosa cells surround the oocyte and provide a protective environment. They are responsible for the nourishment and support of the egg during its development.

3. **Formation of the Secondary Egg Membrane**:
- The secondary egg membrane is formed by the accumulation of granulosa cells around the oocyte. These cells create a protective layer that helps in maintaining the integrity of the egg.

4. **Comparison with Other Cell Types**:
- Other cell types mentioned, such as mucous cells and thecal cells, serve different functions. Mucous cells primarily provide lubrication, while thecal cells are involved in hormone production and follicle development.

5. **Conclusion**:
- Based on the roles and functions of these cells, we can conclude that the secondary egg membrane is primarily formed by granulosa cells.

### Final Answer:
The secondary egg membrane of humans is formed by granulosa cells.
