The meaning of FASCICULATION is muscular twitching involving the simultaneous contraction of contiguous groups of muscle fibers.

Fasciculations are visible, fine and fast, sometimes vermicular contractions of fine muscle fibers that occur spontaneously and intermittently.

Fasciculation, which is spontaneous contraction of the group of muscle fibers that compose a motor unit, is a feature of lower motor neuron disease (e.g., Werdnig-Hoffmann disease).
