WebInside the axon terminal of a sending cell are many synaptic vesicles. These are membrane-bound spheres filled with neurotransmitter molecules. There is a small gap between the axon terminal of the presynaptic neuron and the membrane of the postsynaptic cell, and this gap is called the synaptic cleft. WebThe first category is the unmyelinated axon, which describes all invertebrate axons and small axons of vertebrates, typically axons with a diameter below 1 μm. The unmyelinated axon is usually loosely surrounded by a glial cell or in some cases, such as parallel fibers in the cerebellar molecular layer, is not covered by a glial cell. Webis a very small space between two neurons and is an important site where communication between neurons occurs.
