A neuron, neurone, or nerve cell, is a cell that is excitable, firing electric signals called action potentials. Neurons form neural networks in the nervous system, mainly in the central nervous syste

In the nervous system, a synapse is a structure that allows a neuron to exchange signals with another cell in its immediate vicinity. Synapses can be classified as either chemical or electrical, depen

…neural networks in the nervous system, mainly in the central nervous system. Neurons receive and conduct impulses. They communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic…
