In addition to contractile abilities and the direction of fibers, what is the third characteristic that distinguishes muscle tissue from other tissues?

• A. Striated Texture
• B. Elasticity
• C. Color
• D. Vascularity

Answer: (A)

Striated texture is the distinguishing feature here. The striped appearance of muscle fibers comes from the highly organized arrangement of sarcomeres—the repeating contractile units of actin and myosin—along each fiber. This banding pattern is characteristic of skeletal and cardiac muscle and directly ties to how these muscles generate force. Other tissues don’t show these alternating light and dark bands, so striation is a visual cue that sets muscle apart. Elasticity, color, and vascularity can vary across many tissue types and aren’t unique markers of muscle, whereas striations specifically reflect the organized contractile machinery of muscle tissue.
