A synapse provides a connection between neurons that allows sensory information to flow between them. Sensory information travels along a specialized projection of a neuron until reaching a synapse, which acts like a junction terminal. It's the function of a synapse to allow sensory impulses to travel in a single direction, divide impulses between multiple neurons, or merge impulses onto a single neuron. There are three types of synapses: axodentritic synapses, which are found on dendrites; axosomatic synapses, which are found on cell bodies, and axoaxonic synapses, which are found on axons.
