Myofibrils account for roughly 80% of cellular volume, and are the contractile elements of the muscle cell. Myofibrils consist of repeating units called sarcomeres (the contractile unit of the myofibril), which have overlapping myofilaments connected to Z discs at either end of the sarcomere.
Skeletal muscles move the bones of the body. The functional unit of skeletal muscle is a sarcomere, which consists of thick filaments, called myosin, and thin filaments, called actin. The action of the actin and myosin fibers sliding past one another causes the muscle to contract. The neuromuscular junction is where the nerve cell meets the muscle.
