Long description

This diagram shows some detail of the molecular events at the synapse. The bulb-shaped ends of two neurons are shown in close proximity to each other. The region encompassing them together with the gap between them is labelled the synapse. The axon terminal of the neuron on the left is depicted as containing small triangular-shaped neurotransmitters, some of which are crossing the gap towards the neuron on the right. The bulbed end of the neuron on the right is depicted with complementary triangular shaped wedges cut out. Some of these are filled by the neurotransmitters. These are labelled as unoccupied receptors and occupied receptors, respectively.
