Which muscle type is found in arms and legs and in parts of the body where movement is under conscious control?

• A. Involuntary Muscle
• B. Voluntary Muscle
• C. Cardiac Muscle
• D. Nerve Tissue

Answer: (B)

Movement of the arms and legs comes from skeletal muscles, which are voluntary muscles. These muscles attach to bones and contract under conscious control via the somatic nervous system, letting you decide to bend an elbow, extend a knee, or walk. Involuntary muscles are smooth muscles found in the walls of internal organs and blood vessels, operating without conscious input. Cardiac muscle makes up the heart and isn’t under voluntary control. Nerve tissue isn’t muscle. So the type in limbs that you control consciously is voluntary (skeletal) muscle.
