Ligament consist of

Options

A. Yellow fibres + Elastic fibres
B. Yellow fibres + Collagen (white) fibres
C. Yellow fibres + Muscle fibres
D. White fibres + Muscle fibres

Answer

To determine what ligaments consist of, we can analyze the options provided and the characteristics of ligaments as described in the video transcript.

### Step-by-Step Solution:

1. **Understanding Ligaments**:
- Ligaments are tough, fibrous bands of connective tissue that support internal organs and hold bones together at joints.

2. **Composition of Ligaments**:
- According to the transcript, ligaments are primarily made up of dense fibrous bundles of collagen fibers and spindle-shaped cells known as fibrocytes.

3. **Types of Ligaments**:
- There are two main types of ligaments mentioned:
- **White Ligament**: Rich in collagen fibers, which are sturdy and inelastic.
- **Yellow Ligament**: Rich in elastic fibers.

4. **Analyzing the Options**:
- **Option A**: Yellow fibers plus elastic fibers - This does not accurately describe ligaments since they contain collagen fibers.
- **Option B**: Yellow fibers plus collagen white fibers - This option correctly identifies the presence of both collagen (white fibers) and elastic fibers in ligaments.
- **Option C**: Yellow fibers plus muscle fibers - This is incorrect as ligaments do not contain muscle fibers.
- **Option D**: White fibers plus muscle fibers - This is also incorrect for the same reason as option C.

5. **Conclusion**:
- The correct answer is **Option B**: Yellow fibers plus collagen white fibers.

### Final Answer:
**Ligaments consist of yellow fibers plus collagen white fibers (Option B).**
