Definitions for "Fasciculations"
small local contractions of muscles which can be seen visibly through the skin.
Spontaneous contractions of all the muscle fibers in a motor unit (a fascicle of muscle fibers), which occur in early stages of muscle denervation. They presumably reflect abnormal activity of the motoneuron. Fasciculations can be seen during physical examination if the affected muscle is close to the body surface. They appear as subtle ripples or waves of contraction that pass across the skin surface.
involuntary muscle contractions / twitches.
