Which list accurately names the three basic types of muscle found in the body?

• A. Nervous Tissue; Epithelial Tissue; Connective Tissue
• B. Skeletal Muscle; Cardiac Muscle; Smooth Muscle
• C. Striated Muscle; Voluntary Muscle; Involuntary Muscle
• D. Myofibrils; Myofilaments; Sarcomeres

Answer: (B)

Muscle tissue in the body is organized into three main types: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscle attaches to bones and enables voluntary movement; its fibers are striated due to the arrangement of actin and myosin. Cardiac muscle forms the heart walls; it is also striated but contracts involuntarily and contains intercalated discs that help coordinate heartbeats. Smooth muscle lines the walls of hollow organs and blood vessels; it is non-striated and contracts involuntarily to move substances through organs.

This triple classification is the best answer because it lists three distinct muscle tissues. Other options point to tissue types that aren’t muscles (nervous, epithelial, connective), or describe features (striated, voluntary, involuntary) rather than three separate muscle tissues, or refer to subcellular parts (myofibrils, myofilaments, sarcomeres) rather than whole muscle types.
