All-or-none Response: Phenomenon in which a muscle fiber contracts completely when exposed to a threshold stimulus, or not at all. When a skeletal muscle is stimulated to contract by a motor neuron a minimum amount of stimulus is needed to start the process of muscle contraction.
Skeletal muscle is the only type of muscle that we can consciously control through our nervous system. This is the reason it is also voluntary. Skeletal muscle cells are also long and cylindrical. For this reason a skeletal muscle cell can also be referred to as a skeletal muscle fiber.A skeletal muscle fiber can be up to a foot long! These long, highly specialized cells result from the fusion of many cells and after the cells fuse their individual nuclei are retained.ontraction of a skeletal muscle as a whole depends upon the contraction of individual skeletal muscle cells. An individual skeletal muscle cell will either contract or not contract if it is stimulated. This is referred to as the all or none response.
