Sarcolemma is a membrane found over

Options

A. Nerve fiber
B. Skeletal Muscle Fiber
C. Heart Muscle
D. Heart

Answer

**Step-by-Step Solution:**

1. **Understanding Sarcolemma**: Sarcolemma is a specific term used to describe the cell membrane of muscle fibers. It is important to identify where this membrane is found.

2. **Analyzing the Options**:
- **Option A: Nerve Fibres**: Nerve fibers, or neurons, have a plasma membrane, not a sarcolemma. Therefore, this option is incorrect.
- **Option B: Skeletal Muscle Fibres**: Skeletal muscle fibers are indeed surrounded by a membrane called the sarcolemma. This is a key characteristic of striated muscle cells. Thus, this option is likely correct.
- **Option C: Heart Muscle**: Heart muscle, or cardiac muscle, has its own specific membrane, but it is not referred to as sarcolemma. Therefore, this option is incorrect.
- **Option D: Heart**: The heart itself is an organ and is covered by a protective membrane called the pericardium, not a sarcolemma. Hence, this option is also incorrect.

3. **Conclusion**: Based on the analysis, the correct answer is **Skeletal Muscle Fibres**, as the sarcolemma is the membrane that surrounds these muscle fibers.

**Final Answer**: Sarcolemma is a membrane found over **Skeletal Muscle Fibres**.
