Which of the following are the characteristic of striated muscle?

Options

A. Cylindrical, Striped and branched
B. Cylindrical, Striped and uninucleate
C. Spindle, unbranched and uninucleate
D. Cylindrical, Syncytial and unbranched

Answer

To determine the characteristics of striated muscle, let's analyze the options provided step by step.

### Step 1: Understand the Structure of Striated Muscle
Striated muscles, also known as skeletal muscles, have specific characteristics:
- They are cylindrical in shape.
- They exhibit a striped appearance due to the arrangement of actin and myosin filaments.
- They are unbranched, meaning the muscle fibers do not branch out.
- They are multinucleated, which means each muscle fiber contains multiple nuclei.

### Step 2: Analyze Each Option
Now, let's evaluate each option based on the characteristics of striated muscle:

1. **First Option: Cylindrical, striped, and branched**
- **Analysis**: Striated muscles are cylindrical and striped, but they are not branched. This option is incorrect.

2. **Second Option: Cylindrical, striped, and unnucleated**
- **Analysis**: While striated muscles are cylindrical and striped, they are not unnucleated; they are multinucleated. This option is incorrect.

3. **Third Option: Spindle, unbranched, or nucleated**
- **Analysis**: Striated muscles are not spindle-shaped; they are cylindrical. This option is incorrect.

4. **Fourth Option: Cylindrical, syncytial, or unbranched**
- **Analysis**: This option describes striated muscles accurately. They are cylindrical, syncytial (multinucleated), and unbranched. This option is correct.

### Conclusion
The correct answer is the **fourth option: cylindrical, syncytial, or unbranched**.
