The correct Answer is:
To determine which points are correct regarding skeletal muscles, let's analyze each statement one by one: **Step 1: Analyze Statement (A)** - Statement (A) claims that skeletal muscles are under the voluntary control of the nervous system. - **Correctness**: This statement is true. Skeletal muscles are indeed under voluntary control, meaning we can consciously control their movements. **Step 2: Analyze Statement (B)** - Statement (B) states that skeletal muscles are located in the inner walls of visceral organs. - **Correctness**: This statement is false. Skeletal muscles are not found in the inner walls of visceral organs; that is the role of smooth muscles. **Step 3: Analyze Statement (C)** - Statement (C) asserts that skeletal muscles are primarily involved in locomotory actions and changes of body posture. - **Correctness**: This statement is true. Skeletal muscles are responsible for movements such as walking, running, and maintaining posture. **Step 4: Analyze Statement (D)** - Statement (D) claims that skeletal muscles have no striped appearance. - **Correctness**: This statement is false. Skeletal muscles have a striped or striated appearance due to the arrangement of muscle fibers. **Conclusion:** - The correct statements regarding skeletal muscles are (A) and (C). Therefore, the answer is that statements A and C are correct.
