Number of nuclei present in striped muscle fibre is

Options

A. One
B. Many
C. Two
D. None.

Answer

**Step-by-Step Solution:**

1. **Understanding Striped Muscle Fibers**: Striped muscle fibers, also known as skeletal muscle fibers, are specialized cells that are responsible for voluntary movements in the body. They are characterized by their striated appearance under a microscope.

2. **Shape and Structure**: These muscle fibers are long and cylindrical in shape. Unlike some other types of muscle fibers, striped muscle fibers are unbranched.

3. **Nucleus Count**: A key characteristic of striped muscle fibers is that they are multinucleated. This means that each fiber contains multiple nuclei within a single cell.

4. **Analyzing the Options**: The question provides four options regarding the number of nuclei in striped muscle fibers:
- Option 1: 1
- Option 2: Many
- Option 3: 2
- Option 4: None

5. **Selecting the Correct Option**: Given that striped muscle fibers are multinucleated, the correct option is **Option 2: Many**. The other options (1, 2, and none) are incorrect based on the understanding that these fibers contain multiple nuclei.

6. **Conclusion**: Therefore, the number of nuclei present in striped muscle fibers is many.
