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 sarcolemma is present?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Sarcolemma**:
- Sarcolemma is the cell membrane that surrounds muscle fibers (muscle cells). It plays a crucial role in muscle contraction and the transmission of electrical impulses.

2. **Evaluating the Options**:
- **Option 1: Collagen Fibers**:
- Collagen fibers are structural proteins found in various connective tissues. They provide strength and support but do not contain sarcolemma.
- **Conclusion**: This option is incorrect.

- **Option 2: Muscle Fiber**:
- Muscle fibers are the cells that make up muscle tissue. Each muscle fiber has a sarcolemma, which is essential for its function.
- **Conclusion**: This option is correct.

- **Option 3: Elastin Fibers**:
- Elastin fibers are another type of connective tissue fiber that provides elasticity. They are not related to muscle fibers and do not contain sarcolemma.
- **Conclusion**: This option is incorrect.

- **Option 4: Reticulate Fibers**:
- Reticulate fibers are thin fibers that form a network to support soft tissues and organs. They do not contain sarcolemma.
- **Conclusion**: This option is incorrect.

3. **Final Answer**:
- The only option where sarcolemma is present is **Option 2: Muscle Fiber**.
