| description | small, local, involuntary muscle contractions affecting a small number of muscle fibers, often causing a flicker of movement visible under the skin; fasciculations result from increased irritability of an axon (which in turn is often a manifestation of disease of a motor neuron); this leads to sporadic discharges of all the muscle fibers controlled by the axon in isolation from other motor units |
