  - - - contraction occurs through the sliding filament mechanism
        
        the filaments slide past each other
        
        this happens through excitation contraction coupling and cross-bridge cycle
        
        a neuron releases acetylcholine
        
        chemically gated sodium channels open
        
        the membrane of the muscle fiber depolarizes

        this holds the muscle, gets shorter, and they squeezed together
      - motor neurons send the signals to contract
        
        motor neurons synapse with muscle cells at the neuromuscular junction
        
        electrical messages sent down axon of the motor neuron
