Definitions for fasciculation
This page provides all possible meanings and translations of the word fasciculation
muscular twitching of contiguous groups of muscle fibers
An involuntary muscle twitch, usually localised and temporary.
A fasciculation, or "muscle twitch", is a small, local, involuntary muscle contraction and relaxation which may be visible under the skin or detected in deeper areas by EMG testing. They arise as a result of spontaneous depolarization of a lower motor neuron leading to the synchronous contraction of all of the skeletal muscle fibers within a single motor unit. Fasciculations can happen in any skeletal muscle in the body. Fasciculations have a variety of causes, the majority of which are benign, but can also be due to disease of the motor neurons. Fasciculations are commonly encountered in healthy people and are rarely bothersome. In some cases the presence of fasciculations can be annoying and interfere with quality of life. In such cases, where the remainder of the neurological exam is normal, and EMG testing does not indicate any additional pathology a diagnosis of benign fasciculation syndrome is usually made.
U.S. National Library of Medicine
Involuntary contraction of the muscle fibers innervated by a motor unit. Fasciculations can often by visualized and take the form of a muscle twitch or dimpling under the skin, but usually do not generate sufficient force to move a limb. They may represent a benign condition or occur as a manifestation of MOTOR NEURON DISEASE or PERIPHERAL NERVOUS SYSTEM DISEASES. (Adams et al., Principles of Neurology, 6th ed, p1294)
