Haversian canal occurs in

Options

A. Humerus
B. Pubic
C. Scapula
D. Clavicles

Answer

**Step-by-Step Solution:**

1. **Understanding Haversian Canal**: The Haversian canal is a structure found in bones. It is part of the bone's microstructure and is involved in the supply of blood and nutrients to the bone tissue.

2. **Identifying the Location**: The Haversian canal is located in the outer part of the bone, specifically in the cortical region. This region is dense and forms the outer layer of the bone.

3. **Function of Haversian Canal**: The Haversian canals contain minute blood vessels and nerves. They facilitate communication and transport of nutrients and waste between the bone cells and the bloodstream.

4. **Evaluating the Options**: The question provides four options: humerus, pubic, scapula, and clavicles. We need to determine which of these bones contains Haversian canals.

5. **Analyzing Each Option**:
- **Humerus**: This is the bone of the upper arm that connects the shoulder to the elbow. It is a long bone and contains Haversian canals.
- **Pubic**: This bone is part of the pelvis and does not have Haversian canals.
- **Scapula**: This is the shoulder blade and also does not contain Haversian canals.
- **Clavicles**: These are the collarbones, which do not have Haversian canals either.

6. **Conclusion**: Based on the analysis, the only bone among the options that contains Haversian canals is the **humerus**. Therefore, the correct answer is option number one.
