NettetSynapse definition, a region where nerve impulses are transmitted and received, encompassing the axon terminal of a neuron that releases neurotransmitters in response to an impulse, an extremely small gap across which the neurotransmitters travel, and … NettetSynapses. Synapses are represented as separate pre- and postsynaptic components, located at specific locations on segments. Each segment may have any number of anatomical synapses of any type, and can identify which other segments to which it is pre- or postsynaptic.
