Human Gene Set: HP_MUSCLE_FIBRILLATION


Standard name HP_MUSCLE_FIBRILLATION
Systematic name M37573
Brief description Muscle fibrillation
Full description or abstract Fine, rapid twitching of individual muscle fibers with little or no movement of the muscle as a whole as ascertained by electromyography (EMG). If a motor neuron or its axon is destroyed, the muscle fibers it innervates undergo denervation atrophy. This leads to hypersensitivity of individual muscle fibers to acetyl choline so that they may contract spontaneously. Isolated activity of individual muscle fibers is generally so fine it cannot be seen through the intact skin, although it can be recorded as a short-duration spike in the EMG.
