Refer to the characteristics given below and identify how many are true for a skeletal muscle ?
Uninucleated , branched , dark and light band , actin and myosin filaments , spindle - shaped cells

Options

A. 2
B. 3
C. 4
D. 5

Answer

To determine how many characteristics are true for skeletal muscle, we will evaluate each characteristic listed in the question:

1. **Uninucleated**: This statement is false. Skeletal muscle fibers are multinucleated, meaning they contain multiple nuclei per cell.

2. **Branched**: This statement is also false. Skeletal muscle fibers are unbranched. They are long, cylindrical, and do not exhibit branching like cardiac muscle fibers.

3. **Dark and light bands**: This statement is true. Skeletal muscle is striated, which means it has alternating dark (A bands) and light (I bands) bands due to the arrangement of actin and myosin filaments.

4. **Actin and myosin filaments**: This statement is true. Skeletal muscle fibers contain both actin and myosin filaments, which are essential for muscle contraction.

5. **Spindle-shaped cells**: This statement is false. Skeletal muscle fibers are not spindle-shaped; they are cylindrical in shape. Spindle-shaped cells are characteristic of smooth muscle.

Now, let's summarize the true characteristics:

- True characteristics:
- Dark and light bands
- Actin and myosin filaments

- Total true characteristics: 2

### Final Answer:
There are **2 true characteristics** for skeletal muscle.
