Identify the autoimmune disease and type of muscle involved.

Options

A. Myasthenia gravis , skeletal muscle
B. Myasthenia gravis , smooth muscle
C. Muscular dystrophy , skeletal muscle
D. Muscular dystrophy , smooth muscle

Answer

To solve the question of identifying the autoimmune disease and the type of muscle involved, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Autoimmune Diseases**:
- Autoimmune diseases occur when the body's immune system mistakenly attacks its own cells. In this context, we need to identify which of the given options is classified as an autoimmune disease.

2. **Analyzing the Options**:
- The options provided are:
- Myasthenia Gravis Escalator Muscles
- Myasthenia Gravis Smooth Muscles
- Muscular Dystrophy Escalator Muscles
- Muscular Dystrophy Smooth Muscles
- We need to determine which of these options includes an autoimmune disease.

3. **Identifying Myasthenia Gravis**:
- Myasthenia Gravis (MG) is known as an autoimmune disease where the immune system produces antibodies that interfere with the communication between nerves and muscles. This leads to muscle weakness.

4. **Identifying the Type of Muscle Involved**:
- In Myasthenia Gravis, the muscles that are primarily affected are the skeletal muscles. These are the muscles that are under voluntary control and are responsible for movements.

5. **Conclusion**:
- The correct identification is that the autoimmune disease is **Myasthenia Gravis** and the type of muscle involved is **skeletal muscles**.

### Final Answer:
- **Autoimmune Disease**: Myasthenia Gravis
- **Type of Muscle Involved**: Skeletal Muscles
