And a specific type of neurotransmitter involved in the neuromuscular junction is acetylcholine. So acetylcholine is released into this space known as Arisynaptic cleft. And it goes on and binds to a receptor protein channel found on the muscle cell, the postsynaptic membrane. So it binds onto these channels, it causes these channels to open up and there is an influx of these sodium ions into the cell and that causes the process of depolarization of the membrane and that essentially creates an action potential. And this is what we mean by the signal transduction process. So our electron potential or our action potential, the electric signal is transduced.
