A muscle is a group of cells called fibers‚ and are generally quite big. One muscle fiber has a large amount of myofibrils‚ which are muscle proteins in the shape of cylinders. These myofibrils contain two different types of filaments‚ which run along the axis of the fiber in hexagonal patterns. The two types of filaments are thick and thin filaments. Every thick filament is surrounded by six thin filaments. Both thick and thin filaments are attached to a structure called the Z-line. The Z-line runs

The musculocutaneous nerve continues the wave of axon depolarization to individual muscle fibers via motor units. Each motor unit has so many number of motor nerves that extend to individual muscle fibers by way of a neuromuscular junction called the synapse. When the motor nerve is depolarized‚ acetylcholine is released from the axon terminals at the neuromuscular junction. . The acetylcholine
