Striated and voluntary muscles occur in

Options

A. Trachea
B. Lungs
C. Gall bladder
D. Limbs.

Answer

### Step-by-Step Solution:

1. **Understanding Muscle Types**:
- There are three main types of muscle tissues in vertebrates: skeletal muscles, smooth muscles, and cardiac muscles.
- Skeletal muscles are striated and under voluntary control, meaning they can be consciously controlled.
- Smooth muscles are non-striated and involuntary, meaning they operate without conscious control.
- Cardiac muscles are striated but involuntary, found only in the heart.

2. **Identifying the Question**:
- The question asks where striated and voluntary muscles occur.
- We need to focus on skeletal muscles since they are the only type that is both striated and voluntary.

3. **Analyzing the Options**:
- The options provided are: trachea, lungs, gallbladder, and limbs.
- Trachea, lungs, and gallbladder primarily contain smooth muscles (involuntary) and do not have skeletal muscles.

4. **Determining the Correct Answer**:
- Limbs are the parts of the body that contain skeletal muscles, which are striated and under voluntary control.
- Therefore, the correct answer is **limbs**.

5. **Conclusion**:
- Striated and voluntary muscles occur in the limbs, as they are composed of skeletal muscle tissue.
