WebThe synapse. Structurally, two types of synapses are found in neurons: chemical and electrical. Chemical synapses occur when neural membranes abut very close together, but remain distinct, leaving a space. Electrical synapses occur when membranes are linked together (gap junctions) via specialized proteins that allow the flow of ions from one ... WebAug 1, 2024 · Synapses can vary in size, structure, and shape. And they can be found at different sites on a neuron. For example, there may be synapses between the axon of one cell and the dendrite of another, called axodendritic synapses. They can go from the axon to the cell body, or soma-that’s an axosomatic synapse. Or they may go between two …
