Which muscle tissue type is attached to the skeleton, striated, and voluntary?

• A. Skeletal muscle tissue
• B. Cardiac muscle tissue
• C. Smooth muscle tissue
• D. Nervous tissue

Answer: (A)

Think about what moves and supports the skeleton. Skeletal muscle fibers are anchored to bones by tendons, and their fibers show clear striations from the orderly arrangement of sarcomeres. They are under voluntary control, meaning you consciously decide when to contract them to move a limb or adjust posture. Cardiac muscle is also striated, but it operates involuntarily as the heart’s pump and has intercalated discs that coordinate its activity. Smooth muscle lacks striations and is found in the walls of hollow organs, contracting involuntarily to move contents through the body. Nervous tissue isn’t a muscle at all; it transmits signals and coordinates activities rather than producing contraction. Therefore, the muscle type that fits attached to the skeleton, is striated, and voluntary is skeletal muscle tissue.
