Verified step by step guidance

Begin by understanding the definition of striated muscle. Striated muscle refers to muscle tissue that has a striped appearance due to the arrangement of sarcomeres, which are the basic contractile units within the muscle fibers.
Identify the types of striated muscle. There are two main types: skeletal muscle and cardiac muscle. Skeletal muscle is under voluntary control, while cardiac muscle is involuntary.
Evaluate the statement 'Striated muscle is under voluntary control.' Skeletal muscle, a type of striated muscle, is indeed under voluntary control, meaning you can consciously control its movement.
Consider the statement 'Striated muscle lacks sarcomeres.' This is incorrect because the presence of sarcomeres is what gives striated muscle its characteristic appearance.
Analyze the statement 'Striated muscle is found in the walls of hollow organs.' This is incorrect as smooth muscle, not striated muscle, is typically found in the walls of hollow organs like the intestines and blood vessels.
