Put the following steps in muscle fiber contraction into the correct chronological order An action potential is generated in the muscle fiber s sarcolemma A motor neuron fires an action potential and releases ACh into the synaptic clef Cross bridge cycling occurs ACh binds to receptors on the muscle fiber s sarcolemma resulting in an end plate potential Calcium binds to troponin which results in the myosin binding actin The action potential travels down the T tubules triggering the release of calcium ions
