Which are the three types of muscle tissue?

• A. Skeletal, Smooth, and Cardiac
• B. Cardiac muscle only
• C. Skeletal and Cardiac only
• D. Smooth muscle and connective tissue

Answer: (A)

There are three muscle tissue types: skeletal, smooth, and cardiac. Skeletal muscle attaches to bones and is under voluntary control, giving you deliberate movement; it has a striated, multinucleated appearance. Smooth muscle lines the walls of hollow organs and vessels, contracts involuntarily, and lacks obvious striations. Cardiac muscle forms the heart walls; it is striated like skeletal muscle but contracts involuntarily, with intercalated discs that coordinate rhythmic beating. The other options miss one or more muscle types or include non-muscle connective tissue, so they don’t fit.
