Ligament is mainly made up of :

Options

A. Reticulin
B. Elastin
C. Myosin
D. Collagen

Answer

### Step-by-Step Solution:

1. **Understanding Ligaments**:
- Ligaments are a type of connective tissue in the body that connect bones to other bones at joints. They play a crucial role in stabilizing joints and allowing for a range of motion.

2. **Identifying the Composition of Ligaments**:
- Ligaments are primarily composed of fibrous connective tissue. This tissue is made up of various types of protein fibers.

3. **Analyzing the Options**:
- **Option 1: Reticulene**:
- Reticulene is a type of protein fiber found in connective tissues, but it does not primarily make up ligaments.
- **Option 2: Elastin**:
- Ligaments contain elastin fibers, which provide elasticity and allow ligaments to stretch while maintaining their strength. This is a key component of ligaments.
- **Option 3: Myosin**:
- Myosin is a contractile protein primarily found in muscle tissue and is not a component of ligaments.
- **Option 4: Collagen**:
- Collagen is indeed present in ligaments and provides tensile strength, but it is not the main component when considering the elastic properties of ligaments.

4. **Conclusion**:
- Based on the analysis, the main component of ligaments is elastin fibers. Therefore, the correct answer is **Option 2: Elastin**.
