Which one of the followings is correct pairing of a body parts ant the kind of muscle tissue that moves it ?

Options

A. Iris- Involuntary smooth muscle
B. Heart wall-involuntary unstriated muscle
C. Biceps of upperarm-Smooth muscle fibres
D. Abdominal wall-Smooth muscle

Answer

To solve the question regarding the correct pairing of body parts and the kind of muscle tissue that moves them, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Types of Muscle Tissue**:
- There are three types of muscle tissues:
- Skeletal muscle (voluntary and striated)
- Cardiac muscle (involuntary and striated)
- Smooth muscle (involuntary and non-striated)

2. **Analyze Option A**:
- **Body Part**: Arteries
- **Muscle Tissue**: Involuntary smooth muscle
- **Evaluation**: This pairing is correct because arteries are indeed surrounded by smooth muscle, which is involuntary.

3. **Analyze Option B**:
- **Body Part**: Heart wall
- **Muscle Tissue**: Involuntary unstriated muscle
- **Evaluation**: This pairing is incorrect. The heart wall is made up of cardiac muscle, which is involuntary but striated.

4. **Analyze Option C**:
- **Body Part**: Biceps of the upper arm
- **Muscle Tissue**: Smooth muscle fiber
- **Evaluation**: This pairing is incorrect. The biceps are composed of skeletal muscle, which is striated and voluntary.

5. **Analyze Option D**:
- **Body Part**: Abdominal wall
- **Muscle Tissue**: Smooth muscle
- **Evaluation**: This pairing is also incorrect. The abdominal wall contains skeletal muscle, which is striated and voluntary.

6. **Conclusion**:
- After evaluating all options, the only correct pairing is **Option A**: Arteries with involuntary smooth muscle.

### Final Answer:
The correct pairing of a body part and the kind of muscle tissue that moves it is **Option A: Arteries with involuntary smooth muscle**.
