Expert Solution
Step 1: Introduce about the neurons
Neurons are the cells of the nervous system that are responsible for the generation and transmission of nerve impulses throughout the body. Nerve impulses are generated by the differential concentration of specific ions across the plasma membrane of the neurons.
