Which of the following is not syncytial ?

Options

A. Skeletal muscles
B. Tongue muscles
C. Abdominal muscles
D. Smooth muscles.

Answer

**Step-by-Step Solution:**

1. **Understand the Term "Syncytial":**
- Syncytial refers to a condition where cells fuse together to form a multinucleated structure. This is commonly seen in certain types of muscle tissues.

2. **Identify the Options Given:**
- The options provided are:
1. Skeletal muscles
2. Tongue muscles
3. Abdominal muscles
4. Smooth muscles

3. **Analyze Each Option:**
- **Skeletal Muscles:**
- These muscles are multinucleated and are indeed syncytial. Therefore, this option is not the answer.
- **Tongue Muscles:**
- Tongue muscles are a type of skeletal muscle and are also multinucleated. Hence, this option is not the answer.
- **Abdominal Muscles:**
- Abdominal muscles are also classified as skeletal muscles and are multinucleated. Thus, this option is not the answer.
- **Smooth Muscles:**
- Smooth muscles are characterized by being uninucleated (having only one nucleus) and are not syncytial. Therefore, this is the correct answer.

4. **Conclusion:**
- The option that is not syncytial is **smooth muscles**.

**Final Answer:** Smooth muscles (Option 4)
