WebA postsynaptic cell is a neural cell found after the synaptic cleft. It receives signals from the presynaptic cell. The dendrite, axon, or cell body can work as impulse receivers in the … An electrical synapse is an electrically conductive link between two abutting neurons that is formed at a narrow gap between the pre- and postsynaptic cells, known as a gap junction. At gap junctions, cells approach within about 3.5 nm of each other, rather than the 20 to 40 nm distance that separates cells at chemical synapses. As opposed to chemical synapses, the postsynaptic potential in electrical synapses is not caused by the opening of ion channels by chemical transm…
