WebNeuromuscular junction disorder resulting from myasthenia gravis causes a failure of neuromuscular transmission with increasing use (p. 110). The electrophysiological equivalent of fatiguability is the decline in amplitude of the compound motor action potential on repetitive stimulation of the motor nerve. WebThe physiology of the neuromuscular junction is important not only in diseases of this region, but is also implicated in other diseases including critical illness, amyotrophic lateral sclerosis (ALS), muscular dystrophy, spinal muscular atrophy (SMA), sarcopenia, and aging. 21 Neuromuscular junction degeneration and loss is known to occur in ...
