White collagenous fibrous tissue in skin dermis, sheath of cartilage and bone, eyeball are in form of :

Options

A. Irregular dense connective tissue
B. Regular dense connective tissue
C. Tendon
D. Ligament

Answer

To solve the question regarding the type of collagenous fibrous tissue found in the skin dermis, sheath of cartilage and bone, and the eyeball, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**:
The question asks about the form of collagenous fibrous tissue present in specific anatomical locations: skin dermis, sheath of cartilage and bone, and the eyeball.

2. **Identifying the Types of Connective Tissue**:
- **Irregular Dense Connective Tissue**: This type has fibers that are not arranged in parallel bundles. It provides strength in multiple directions.
- **Regular Dense Connective Tissue**: This type has fibers arranged in parallel bundles, providing strength in one direction.
- **Tendons**: These connect muscles to bones and are made of regular dense connective tissue.
- **Ligaments**: These connect bones to other bones and are also made of dense connective tissue, but they can be regular or irregular depending on their function.

3. **Analyzing the Options**:
- **Option A (Irregular Dense Connective Tissue)**: This is not the correct answer because the tissues mentioned have fibers arranged in a specific way.
- **Option B (Regular Dense Connective Tissue)**: This is the correct answer as the collagenous fibrous tissue in the dermis, cartilage, bone, and eyeball is arranged in parallel bundles, providing strength and support.
- **Option C (Tendons)**: While tendons are made of regular dense connective tissue, they are specifically for muscle attachment, not the tissues mentioned in the question.
- **Option D (Ligaments)**: Similar to tendons, ligaments are also fibrous connective tissues but are not the correct answer for the tissues specified in the question.

4. **Conclusion**:
Based on the analysis, the correct answer is **Regular Dense Connective Tissue** (Option B).

### Final Answer:
The white collagenous fibrous tissue in the skin dermis, sheath of cartilage and bone, and eyeball is in the form of **Regular Dense Connective Tissue**.
