Synaptic Transmission. In a chemical synapse, the pre and post synaptic membranes are separated by a synaptic cleft, a fluid filled space. The chemical event is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons. The neurotransmitter termination can occur in three ways - reuptake, enzymatic degradation in the cleft and diffusion.
