Which of the following bone is a favoured site for obtaining haemopoietic tissue ?

Options

A. Radius
B. Vertebral column
C. Cranium
D. Sternum

Answer

To solve the question regarding which bone is a favored site for obtaining hemopoietic tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Hemopoietic Tissue**:
- Hemopoietic tissue is responsible for the production of blood cells, including red blood cells (RBCs). This process is known as hemopoiesis.

2. **Evaluate the Options**:
- We need to analyze the given options to identify which bone is associated with hemopoiesis.

3. **Option Analysis**:
- **Option A: Radius**:
- The radius is a bone in the forearm. It primarily aids in the movement of the wrist and hand. It does not play a role in hemopoiesis.
- **Conclusion**: Incorrect option.

- **Option B: Vertebral Column**:
- The vertebral column protects the spinal cord and provides structural support. It is not primarily involved in the production of blood cells.
- **Conclusion**: Incorrect option.

- **Option C: Cranium**:
- The cranium is the skull that encases the brain. Like the previous options, it does not contribute to hemopoiesis.
- **Conclusion**: Incorrect option.

- **Option D: Sternum**:
- The sternum, or breastbone, is located in the center of the chest and is part of the rib cage. It contains red bone marrow, which is a key site for hemopoiesis, making it a favored site for obtaining hemopoietic tissue.
- **Conclusion**: Correct option.

4. **Final Answer**:
- The favored site for obtaining hemopoietic tissue is the **sternum**.
