The muscles that resemble striped muscles structurally and visceral muscles functionally are  

Options

A. cardiac
B. non straited
C. striated
D. none of the above

Answer

To solve the question, "The muscles that resemble striped muscles structurally and visceral muscles functionally are," we can follow these steps:

### Step-by-Step Solution:

1. **Understand Muscle Types**:
- There are three main types of muscles: skeletal (striated), cardiac, and smooth (visceral).
- Skeletal muscles are striated and under voluntary control.
- Smooth muscles are non-striated and function involuntarily (visceral).
- Cardiac muscles are striated but function involuntarily.

2. **Identify Structural Characteristics**:
- **Striated Muscles**: These muscles have a striped appearance due to the arrangement of actin and myosin filaments. Skeletal and cardiac muscles are striated.
- **Non-Striated Muscles**: These muscles do not have a striped appearance. Smooth muscles fall into this category.

3. **Identify Functional Characteristics**:
- **Voluntary Muscles**: These muscles can be controlled consciously (e.g., skeletal muscles).
- **Involuntary Muscles**: These muscles operate without conscious control (e.g., smooth and cardiac muscles).

4. **Analyze the Options**:
- **Cardiac Muscle**: It is striated (like skeletal muscle) and functions involuntarily (like smooth muscle).
- **Non-Striated Muscle**: This refers to smooth muscle, which does not resemble striated muscle.
- **Striated Muscle**: This is a general term that could refer to skeletal or cardiac muscle but does not specify the involuntary function.
- **None of the Above**: This option is incorrect as we have identified a suitable answer.

5. **Conclusion**:
- The muscle that resembles striped muscles structurally (striated) and visceral muscles functionally (involuntary) is the **cardiac muscle**.

### Final Answer:
The correct answer is **cardiac muscle**.
