The Study of Neurons and Satellite Cells Under an Electron Microscope. Methodological Approaches

Abstract

The main contribution of electron microscopy was the solution of problems concerning Nissl's substance, the Golgi apparatus, neurofibrils, myelin sheath and synapses. However, many problems remain unresolved due to the special nature of the neuron and the complexity of the structure of its processes. The use of an electron microscope led to the emergence of ideas about the structure and functions of the endoplasmic reticulum, protein, myelin sheath, Schwann cells, nodes of Ranvier, synapses, and the contents of presynaptic endings. This article presents the elements of the peripheral nervous system, new information about them and functions that can be further used in the study of the mechanisms of the occurrence of diseases and methods of treatment.
