The nervous system only exists in animals. Neurons are the nerve cells that compose the nervous system.
The neuron´s principal function is to catch stimuli from the exterior convert them into nerve impulses that get transported to the control centers. These control centers interpret the signal and send an answer to the stimuli.
The control centers in invertebrates are ganglia, while the vertebrate´s control centers are the spinal medulla and the encephalon.
The signal transport occurs from cell to cell in inferior animals and through nerves in superior animals.
