In hyaline cartilage , matrix is

Options

A. Granular
B. Transparent
C. Agranular
D. Semitransparent.

Answer

### Step-by-Step Solution:

1. **Understanding Hyaline Cartilage**:
- Hyaline cartilage is a type of connective tissue found in various parts of the body, including the joints, rib cage, and respiratory tract.

2. **Composition of Hyaline Cartilage**:
- The primary component of hyaline cartilage is type II collagen. This collagen provides strength and support.
- Additionally, hyaline cartilage contains chondroitin sulfate, which is a type of glycosaminoglycan that helps in maintaining the cartilage structure.

3. **Meaning of 'Hyaline'**:
- The term 'hyaline' literally means "glass-like." This indicates that hyaline cartilage has a translucent appearance.

4. **Physical Properties of the Matrix**:
- The matrix of hyaline cartilage is not opaque; it is translucent, which means it allows light to pass through but is not completely clear. This gives it a semi-transparent appearance.

5. **Function of Hyaline Cartilage**:
- It provides mechanical support and flexibility to the structures it supports, such as the articulating surfaces of bones, the trachea, and the bronchi.

6. **Evaluating the Options**:
- **Granular**: Incorrect, as hyaline cartilage does not have granular components.
- **Transparent**: Incorrect, as it is not completely transparent.
- **Agranular**: Incorrect, as this term does not accurately describe the matrix.
- **Semi-transparent**: Correct, as it accurately describes the translucent nature of the hyaline cartilage matrix.

7. **Conclusion**:
- The correct answer to the question "In hyaline cartilage, the matrix is" is **semi-transparent**.
