Neuroglia of the peripheral nervous system are part of the nervous tissue in the peripheral part of the nervous system, namely in the composition of Schwann cells and neuroglial cells. Neurons are arranged heterarchically according to their functions. Neurophysiology, the microscopic structure of nerve cell structures, such as the ganglion, peripheral sensory elements and others, is extremely diverse, which allows us to conclude that nervous tissue consists of several different components combined into the nervous system.
