Expert Solution

Step 1

Neurons are the functional and structural units of the nervous system. These cells are capable of perceiving environmental stimuli and then transmitting this in the form of an electrical impulse to the nearby neurons or muscle fibers. These neural cells perceive stimuli with the help of dendrites, transmit them along the entire length of the axon until it reaches the axon terminal. At the axon terminal, the neurotransmitter is released into the synapse from where the signal passes to nearby neurons.
