Which system comprises Skeletal Muscle, Smooth Muscle, and Cardiac Muscle?

• A. Nerves
• B. Skeletal Muscle, Smooth Muscle, Cardiac Muscle
• C. Blood Vessels
• D. Ligaments

Answer: (B)

The muscular system is made up of three muscle tissue types—skeletal, smooth, and cardiac—all working together to create movement, support, and regulate bodily functions. Skeletal muscle attaches to bones and enables voluntary movements; smooth muscle lines hollow organs and blood vessels to control involuntary actions; cardiac muscle forms the heart and drives circulation. The option that lists all three muscle types is identifying the muscular system, which is why it’s the best choice. The other options point to different systems or structures: nerves relate to the nervous system, blood vessels to the circulatory system, and ligaments to connective tissue.
