Action potential travels from motor neuron cell body along the myelinated axon to neuromuscular junction. 2. Acetylcholine (ACh) is released from axon (neuron), crosses synapse (space between axon and sarcolemma).ACh binds to ACh receptors (channel) in sarcolemma. 3.ACh channels open. Ions (like sodium, Na+) flow into sarcolemma.Action potential spreads in sarcolemma and into transverse tubules. 4. Action potential causes the release of calcium (Ca2+) from sarcoplasmic reticulum into sarcoplasm 5.Ca2+ goes to the troponin, which moves the tropomyosin away from actin 6.
