[Anatomy and physiology of the peripheral nerve].
The peripheral nerve provides the pathway for motor, sensory and vegetative axons belonging to the peripheral nervous system. It transmits information between these neurons and their peripheral effectors in both directions (sensory receptors, skeletal muscles and viscera). The afferences to the periphery correspond to the nerve motor content, whereas efferences from the periphery, in charge of delivering information to the central integrators, correspond to nerve-sensitive content. This information support depends on intrinsic properties of the nerve itself. Recent advances in cellular and molecular biology have provided a better understanding of nerve physiology, which are reviewed here as an indispensable basis to the study of its pathology.
