single, spontaneous, involuntary discharge of an individual motor unit.
a small local contraction of muscles, visible through the skin, representing a spontaneous discharge of a number of fibres innervated by a single motor nerve filament. In association with compression of the spinal cord, ventral roots or anterior horns of grey matter, fasciculation of the muscles innervated by the affected segments will occur, along with progressive wasting and weakness.
Twitching of the muscles that is seen in diseases involving the peripheral nervous system.
An arrangement of fasciculi (see below), or a form of muscular contraction consisting of involuntary contractions or twitchings of groups of muscle fibers.
Involuntary contractions or twitchings of groups of muscle fibers. Fasciculations can occur in normal individuals without an associated disease or condition and can also occur as a result of illness, such as muscle cramps, nerve diseases, and metabolism imbalances.
Small, involuntary, irregular, visible contractions of individual muscle fibers. Often seen in the legs, arms and shoulders of PALS.
Involuntary contractions, or twitchings, of groups (fasciculi) of muscle fibers, a coarser form of muscular contraction than fibrillation.Febrile - Denoting or relating to fever.
twitching; non-painful, rapid and involuntary contractions of groups of muscles fibers. This is often described by people with ALS as “ persistent rolling beneath the skin.” (11).
A fasciculation (or "muscle twitch") is a small, local, involuntary muscle contraction (twitching) visible under the skin arising from the spontaneous discharge of a bundle of skeletal muscle fibers. Fasciculations have a variety of causes, the majority of which are benign.
