The occurrence and distribution of the AcPase activity expressed within the axon differed depending on neuron type and distance from the cell body. Both in alpha-motor and DRG neurons, AcPase-positive bodies of various morphological categories were observed mainly at nodes of Ranvier, where they ...
Junctions that are formed between the axon and the myelinating cell (called the paranodal junctions) border the nodes of Ranvier. In this region, the compact myelin lamellae open up into a chain of cytoplasmic loops that form a series of septate-like junctions with the axon (Rosenbluth 1995...
