Which one of the following has alternate striations and is branched?

Options

A. Biceps under autonomous control
B. Iris muscle under control of will
C. Heart muscle, involuntary
D. Muscle of visceral organs under autonomous control

Answer

To solve the question "Which one of the following has alternate striations and is branched?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Striations** refer to the striped appearance of certain muscle tissues, which is indicative of their structure and function.
- **Branched** refers to the muscle fibers that split into branches, which is a characteristic of certain types of muscle tissue.

2. **Identify Muscle Types**:
- There are three main types of muscle tissue:
- **Skeletal Muscle**: Striated and voluntary, but not branched.
- **Cardiac Muscle**: Striated and branched, involuntary control.
- **Smooth Muscle**: Non-striated and involuntary, not branched.

3. **Analyze the Characteristics**:
- Since we are looking for a muscle that is both striated and branched, we can eliminate skeletal muscle and smooth muscle based on their characteristics.
- Cardiac muscle fits the criteria as it has both striations and branching.

4. **Location of Cardiac Muscle**:
- Cardiac muscle is specifically located in the walls of the heart and is responsible for pumping blood throughout the body.

5. **Conclusion**:
- Based on the analysis, the correct answer to the question is **Cardiac Muscle** (often referred to as heart muscle), which is involuntary and has both alternate striations and branching.

### Final Answer:
The correct answer is **Cardiac Muscle**.
