Thrombocytes are cell fragments produced from

Options

A. dendritic cells
B. myeloblasts
C. megakaryocytes
D. macrophages

Answer

**Step-by-Step Solution:**

1. **Understanding Thrombocytes**: Thrombocytes, commonly known as platelets, are essential components of blood that play a crucial role in the clotting process.

2. **Identifying the Source**: Thrombocytes are not whole cells but rather cell fragments. They are produced from larger precursor cells.

3. **Recognizing the Precursor Cell**: The specific precursor cell that gives rise to thrombocytes is known as megakaryocytes. These are large cells found in the bone marrow.

4. **Eliminating Incorrect Options**:
- **Dendritic Cells**: These are involved in the immune response and are not related to platelet production.
- **Megaloblasts**: These are immature red blood cells and do not produce platelets.
- **Macrophages**: These are immune cells that engulf pathogens and debris, not involved in the formation of platelets.

5. **Conclusion**: Since the only correct option that produces thrombocytes is megakaryocytes, the answer to the question is that thrombocytes are cell fragments produced from megakaryocytes.

**Final Answer**: Thrombocytes are cell fragments produced from **megakaryocytes**.
