If a muscle is described as striated, what does that indicate about its appearance?

Explanation:
Striated means striped, because the muscle fibers have a regular arrangement of actin and myosin in repeating units called sarcomeres that create alternating light and dark bands. This banded appearance is what defines striated muscle, visible in skeletal and cardiac types. Smooth muscle, in contrast, lacks these bands and looks uniform; the terms round or not visible don’t describe the striped pattern.
