Special cells in the bone marrow that produce thrombocytes are

Options

A. B cells
B. T cells
C. Megakaryocytes
D. Monocytes

Answer

To solve the question regarding the special cells in the bone marrow that produce thrombocytes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Thrombocytes**:
- Thrombocytes are also known as platelets. They are crucial components of blood that play a significant role in the clotting process, helping to prevent excessive blood loss when there is an injury.

2. **Identifying the Cell Types**:
- The question provides several options: beta cells, T cells, megakaryocytes, and monocytes.
- It is important to recognize the function of each of these cell types:
- **Beta cells**: These are involved in the production of insulin in the pancreas.
- **T cells**: These are a type of white blood cell that plays a central role in the immune response.
- **Monocytes**: These are also a type of white blood cell that differentiates into macrophages and dendritic cells to help fight infections.
- **Megakaryocytes**: These are large bone marrow cells responsible for the production of platelets.

3. **Locating the Correct Cell**:
- Among the options, megakaryocytes are specifically known for their role in producing thrombocytes (platelets). They are found in the red bone marrow and are the only cells that give rise to platelets.

4. **Conclusion**:
- Therefore, the special cells in the bone marrow that produce thrombocytes are **megakaryocytes**.

### Final Answer:
The special cells in the bone marrow that produce thrombocytes are **megakaryocytes**.
