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 combination of a motor nerve and the group of muscle fibers that it innervates is called the motor unit. Each branch of a motor nerve in a motor unit extends to a separate muscle fiber. All the muscle fibers that constitute such a unit contract almost simultaneously when they are excited.n muscle cells myosin is arranged in long filaments called thick filaments that lie parallel to the microfilaments of actin......
