Describe the steps of how cross-bridge musclecontractions take place using the followinggeneral information
1) Action potential (generated by motor neuron) innervatesmuscle fiber
2) Motor neuron releases neurotransmitter (travels acrossneuromuscular junction), binds to muscle cell (sarcolemma)
3) Action potential in muscle fiber allows sliding ofmyofilaments (shortening of muscle cells)
