Answer 44

Brain sends impulse down to a motor neuron, once it reaches the end Acetylcholine is released into the Synaptic Cleft, Acetylcholine binds to special protein receptors on the muscle cell which causes an electric impulse to spread all over the cell, sarcomere shorten and muscle contracts

In pairs
