In the body, two types of the synapses occur, chemical and the electrical. The chemical synapses are the most common type of synapse. The chemical synapse works by the release of chemicals from presynaptic neuron and the binding of the chemical messenger to the receptors of the post synaptic neuron.
The binding of the neuron may result in different effects in the post synaptic neuron, it may be inhibitory or excitatory, depending on the messenger. Hence, the chemical synapse provides a variety of signals. In case of electric synapse, the signals will always excite the post neuron, which may not be required sometimes. Hence, the electrical signals will not provide the inhibition of the post synaptic neuron.
