There are three main categories of vertebrate muscles. Skeletal muscles control body movement and are innervated by motor neurons at the neuromuscular junction. Movement requires coordinated contraction of antagonistic muscle groups. Diseases like myasthenia gravis and Parkinson's disease impact muscle function and movement by disrupting signaling at the neuromuscular junction or depleting dopamine in the basal ganglia.
