Question

Quizplus · Accepted Answer

The striated patterns seen in skeletal muscle are caused by the aligned borders of sarcomeres, which are the basic contractile units of muscle fibers. These patterns are due to the arrangement of actin and myosin filaments within the sarcomeres, leading to the appearance of light and dark bands.
