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.
The functional units of skeletal muscle are not individual muscle fibers, but larger systems called motor units. The motor unit consists of a motor neuron and the group of skeletal muscle fibers which it innervates. A single skeletal muscle is composed of many thousands to millions of long, narrow contractile cells called muscle fibers (Fig-1). These fibers are clustered together in parallel bundles called fasciculi.
