The nervous system consists of two parts that differ in their physiology and function. Neurons of the peripheral nervous system (PNS) receive information from the external environment and carry signals to and from the brain and spinal cord, which constitute the central nervous system (CNS).
Peripheral neurons consist of a cell body and a long process, or axon, which may lead one meter in length. Short segments of the axon are wrapped with an insulating myelin sheath formed by Schwann (...)
