Process of contraction in skeletal muscles The process of contraction take splace by various roles steps involning 1 a nerve impulse which travels to the neromuscular junction on a muscle is the point where axons of the nerve cells meet the muscle cell 2 The axon relaeses ACh to the rreceptors located on the sarcolemma This act causes depolarization of the sarcolemma by openeing the ion channels and allows the Na ions into the muscle cells 3 These Na ions diffuses into the muscle fiber and depolarization continues as it creates an action potential from motor neuron across the sarcolemma which triggers the release of acetylcholine into the motor end plate 4 The action potential travels across the sarcolemma and down the Ttubules and triggers the sarcoplasmic reticulum to release Ca See Answer
