Smooth muscles are

Options

A. involuatary, fusiform, non-triated
B. voluntary, multinucleate, cylinderqinvluntary, cylinderical, striated
C. Involuntary, cyinderical, striated
D. voluntary, spindle-shaped, uninucleate

Answer

To answer the question about smooth muscles, we will analyze the characteristics of smooth muscle tissue and identify the correct option from the given choices.

### Step-by-Step Solution:

1. **Identify the Type of Muscle**:
- Smooth muscles are one of the three types of muscle tissues in the body, the other two being skeletal and cardiac muscles.

2. **Characteristics of Smooth Muscles**:
- **Involuntary**: Smooth muscles are not under conscious control, meaning they function automatically (e.g., in the walls of organs).
- **Shape**: Smooth muscle cells are fusiform (spindle-shaped), which means they are wider in the middle and taper at both ends.
- **Striation**: Smooth muscles are non-striated, meaning they do not have the banded appearance seen in skeletal muscles.

3. **Analyze the Options**:
- The options given are:
1. Involuntary, fusiform, and non-striated
2. Voluntary, multinucleated, and slantical
3. Involuntary, slantical-striated
4. Voluntary, spindle shape, and uninucleated

4. **Match Characteristics to Options**:
- The first option matches the characteristics of smooth muscles: **involuntary**, **fusiform**, and **non-striated**.
- The second option describes features of skeletal muscles (voluntary and multinucleated).
- The third option incorrectly describes smooth muscles.
- The fourth option describes features that do not accurately represent smooth muscles.

5. **Conclusion**:
- The correct answer is the **first option**: **involuntary, fusiform, and non-striated**.

### Final Answer:
Smooth muscles are **involuntary, fusiform, and non-striated**.
