Which of the following is incorrect about the skeletal muscle?

Options

A. Not under direct control of CNS
B. These are primarily involved in locomotion
C. Voluntary nature
D. Possess stripped appearance

Answer

To solve the question regarding the incorrect statement about skeletal muscles, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Skeletal Muscles**: Skeletal muscles are a type of striated muscle tissue that is under voluntary control. They are primarily responsible for movement and locomotion in the body.

2. **Analyzing the Statements**:
- **Statement 1**: "Skeletal muscles are not under direct control of the brain."
- This statement is incorrect. Skeletal muscles are indeed under the control of the central nervous system (CNS), which includes the brain. Therefore, this statement is false.

- **Statement 2**: "Skeletal muscles are primarily involved in locomotion."
- This statement is true. Skeletal muscles are attached to bones and facilitate movement, making them essential for locomotion.

- **Statement 3**: "Skeletal muscles are voluntary in nature."
- This statement is also true. Skeletal muscles are classified as voluntary muscles because their contraction is consciously controlled by the CNS.

- **Statement 4**: "Skeletal muscles possess a striated appearance."
- This statement is true as well. Skeletal muscles have a striated appearance due to the alternating dark and light bands formed by the arrangement of thick and thin filaments.

3. **Conclusion**: The only incorrect statement among the options provided is the first one, which states that skeletal muscles are not under direct control of the brain.

### Final Answer:
The incorrect statement about skeletal muscles is: "Skeletal muscles are not under direct control of the brain."
