WebA single efferent neuron and all of the muscle fibers that it controls is called a motor unit. Thus each muscle contains many motor units, and not all motor units are necessarily activated at the same time. The more motor units are active, the larger the number of muscle fibers that contract, and the greater the degree of muscle contraction. WebA specialized cell that can produce force and movement is a muscle cell, commonly referred to as a myocyte or muscle fiber. Long and cylindrical in structure, muscle cells have many nuclei that are situated on the cell's edge. They are divided into three groups: skeletal, cardiac, and smooth, each of which has particular traits and purposes.
