acetylcholine is released from the end of the motor neuron. The first event in muscle fiber contraction is that. -the muscle fiber membrane is stimulated and a muscle impulse travels deep into the fiber through transverse tubules. -acetylcholine diffuses across a gap at a neuromuscular junction. -acetylcholine is released from the end of the motor neuron.
