Cross connections are the characteristic feature of

Options

A. Cardiac muscles
B. Striated muscles
C. Smooth muscles
D. None of the above.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks about the characteristic feature of cross connections. We need to identify which type of muscle tissue exhibits this feature.

2. **Identifying Muscle Types**: There are three main types of muscle tissue in the body: skeletal muscle, smooth muscle, and cardiac muscle. Each has distinct characteristics.

3. **Examining Cardiac Muscle**: Cardiac muscle is found specifically in the walls of the heart. It is unique compared to skeletal and smooth muscles.

4. **Characteristics of Cardiac Muscle**:
- Cardiac muscle fibers are striated, meaning they have a striped appearance.
- The fibers are interconnected by structures known as intercalated discs, which are the cross connections referred to in the question.

5. **Function of Cross Connections**: These cross connections allow for synchronized contraction of the heart muscle, enabling it to pump blood effectively throughout the body.

6. **Conclusion**: Based on the characteristics and functions of cardiac muscle, we conclude that cross connections are indeed a characteristic feature of cardiac muscle.

**Final Answer**: Cross connections are a characteristic feature of cardiac muscle.
