How many types of muscle tissue are described in the material?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The question tests how the material classifies muscle tissue. In this material, muscle tissues are grouped by control: voluntary and involuntary. The voluntary type (skeletal) is the one you can consciously move, such as muscles that attach to bones and help you lift, run, and squat. The involuntary type includes muscles that work automatically—these are the smooth muscles in the walls of hollow organs and the cardiac muscle in the heart—controlled without conscious effort.

Because the material describes two broad categories based on whether you control them, two types of muscle tissue are described. It’s common to encounter three distinct tissue types in anatomy (skeletal, smooth, cardiac), but some courses or sections lump the two involuntary tissues together under a single umbrella when focusing on control rather than microscopic structure. That’s why the answer reflects two.
