Which identifies striated muscles ?

Options

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

Answer

### Step-by-Step Solution:

1. **Understand the Types of Muscles**:
- There are three main types of muscles in vertebrates: skeletal, cardiac, and smooth muscles.

2. **Identify Characteristics of Striated Muscles**:
- Striated muscles are also known as skeletal muscles. They are characterized by the presence of striations (stripes) and are under voluntary control.

3. **Define the Structure of Skeletal Muscles**:
- Skeletal muscle fibers are cylindrical in shape, have striations, and are unbranched. Additionally, they are multinucleated, meaning each fiber contains multiple nuclei.

4. **Analyze the Options Given**:
- The options provided are:
- a) cylindrical, striped and branched
- b) cylindrical, striped and uninucleated
- c) spindle, unbranched and uninucleated
- d) cylindrical, striped and unbranched

5. **Eliminate Incorrect Options**:
- Option a (cylindrical, striped and branched) is incorrect because skeletal muscles are unbranched.
- Option b (cylindrical, striped and uninucleated) is incorrect because skeletal muscles are multinucleated.
- Option c (spindle, unbranched and uninucleated) is incorrect because it describes smooth muscle characteristics.

6. **Select the Correct Option**:
- The only option that correctly describes striated (skeletal) muscles is option d: **cylindrical, striped and unbranched**.

### Final Answer:
The correct identification of striated muscles is **cylindrical, striped and unbranched**.
