Options

A. They are the most abundant type of muscle found in the body
B. They undergo rapid contraction
C. They do not get tired
D. They are found attached to bones

Answer

To find the incorrect statement regarding skeletal muscles, we will evaluate each statement provided.

1. **Statement 1**: Skeletal muscles are the most abundant type of muscles found in the body.
- **Evaluation**: This statement is true. Skeletal muscles are indeed the most abundant type of muscle in the human body, found in various locations such as limbs, body walls, tongue, pharynx, and the beginning of the esophagus.

2. **Statement 2**: Skeletal muscles are striated muscles because of the presence of dark and light bands in their structure.
- **Evaluation**: This statement is also true. Skeletal muscles exhibit a striated appearance due to the arrangement of actin and myosin filaments, which create alternating dark (A bands) and light (I bands) bands.

3. **Statement 3**: Skeletal muscles do not get tired.
- **Evaluation**: This statement is incorrect. Skeletal muscles can get fatigued, especially after prolonged activity. Fatigue occurs due to the accumulation of lactic acid and other factors, leading to muscle cramps and a decrease in performance.

4. **Statement 4**: Skeletal muscles are found attached to the bones.
- **Evaluation**: This statement is true. Skeletal muscles are attached to bones via tendons and are responsible for voluntary movements of the skeleton.

Based on the evaluations, the incorrect statement regarding skeletal muscles is **Statement 3**: "Skeletal muscles do not get tired."

### Summary of the Solution:
- Statement 1: True
- Statement 2: True
- Statement 3: **Incorrect**
- Statement 4: True

**Final Answer**: The incorrect statement is Statement 3.
