"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 … " - Describe the structure of synapses
