In which of the following sarcolemma is present ?

Options

A. Collagen fibres
B. Muscle fibres
C. Elastin fibres
D. Reticulate fibres

Answer

To solve the question "In which of the following is sarcolemma present?", we will analyze the options provided and determine which one contains sarcolemma.

### Step-by-Step Solution:

1. **Understanding Sarcolemma**:
- Sarcolemma is the cell membrane surrounding a muscle fiber. It acts as a barrier between the extracellular environment and the intracellular components of the muscle cell.

2. **Analyzing the Options**:
- **Option 1: Collagen Fiber**:
- Collagen fibers are structural proteins found in various tissues, providing strength and support. They do not contain sarcolemma.
- **Option 2: Muscle Fiber**:
- Muscle fibers are the cells that make up muscle tissue. Each muscle fiber is surrounded by a sarcolemma, making this option a strong candidate.
- **Option 3: Elastin Fiber**:
- Elastin fibers provide elasticity to tissues but do not have sarcolemma. They are not related to muscle fibers directly.
- **Option 4: Reticulate Fiber**:
- Reticulate fibers form a mesh-like structure in various tissues but do not contain sarcolemma.

3. **Conclusion**:
- Based on the analysis, the only option that contains sarcolemma is **Option 2: Muscle Fiber**.

### Final Answer:
- The correct answer is **Muscle Fiber**.
