How Neurons Signal at Synapses

Neurons communicate through synapses, the points where two neurons meet to pass on signals. At a synapse, the sending neuron is the presynaptic cell, and the receiving neuron is the postsynaptic cell. Most neurons can serve in both roles because they send and receive information.

The cells of your nervous system are constantly receiving and transmitting information, from basic bodily function to sensory stimulus. Neurons communicate with electrical signals called action potentials. These action potentials originate in the cell body and travel along the axon to the axon terminal where they are passed on to the next cell.<...
