This image of the synaptic cleft between two neurons was created by Cynthia S. Gordon of MedAnimations for Dr. Kenny Handelman at Medical Integrity, Inc.

The presynaptic ending of the axon is shown containing neurotransmitters and mitochondria. Also shown is the diffusion of neurotransmitter molecules across the synapse to receptor sites on the postsynaptic dendrite.
