Sarcolemma is the membrane that covers

Options

A. nerve fibres
B. muscle fibres
C. visceral fibres
D. tendons

Explanation

**Step-by-Step Solution:**

1. **Understanding Sarcolemma**: The sarcolemma is a specific type of membrane that is found in muscle fibers. It is essential for the structure and function of muscle cells.

2. **Identifying Muscle Fibers**: Muscle fibers are long, narrow, and cylindrical cells that make up muscle tissue. Each muscle fiber requires a protective covering.

3. **Comparison with Plasma Membrane**: The sarcolemma functions similarly to a plasma membrane, which is the outer boundary of all cells. However, in muscle cells, this membrane is specifically referred to as the sarcolemma.

4. **Components of Sarcolemma**: The sarcolemma is rich in blood supply and contains a high concentration of ATP (adenosine triphosphate), which is crucial for muscle contraction and energy.

5. **Conclusion**: Based on the information, we can conclude that the sarcolemma covers muscle fibers. Therefore, the correct answer to the question is that the sarcolemma is the membrane that covers muscle fibers.

**Final Answer**: Sarcolemma is the membrane that covers muscle fibers.
