Muscle Contraction

This tutorial will help students understand the process of muscle contraction. A muscle contains many muscle fibers and each fiber contains a bundle of 4-20 myofibrils. Each fibril is striated and these striations are produced by the arrangement of thick and thin filaments, called actin and myosin. The contraction and relaxation of these actin and myosin filaments help muscles move.
