Los nervios son estructuras conductoras de impulsos nerviosos situadas fuera del sistema nervioso central. Están formados por un conjunto de axones agrupados, cada uno de los cuales procede de una neurona. Pueden ser motores o sensitivos, pero la mayor parte son mixtos y contienen tanto fibras sensitivas como motoras.
12 de sept. de 2024 · Los nervios que transmiten señales del cerebro se llaman nervios motores o eferentes, y los que transmiten información del cuerpo al sistema nervioso central se denominan sensitivos o aferentes. A nivel celular, el sistema nervioso se define por la presencia de un tipo de célula llamada neurona, o “célula nerviosa”.
Nerve, in anatomy, a glistening white cordlike bundle of fibers, surrounded by a sheath, that connects the nervous system with other parts of the body. The nerves conduct impulses toward or away from the central nervous mechanism. In humans 12 pairs are attached to the brain and 31 pairs to the spinal cord.
Nerves have historically been considered the basic units of the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses called action potentials that are transmitted along each of the axons to peripheral organs or, in the case of sensory nerves , from the periphery back to the central ...

The nervous system derives its name from nerves, which are cylindrical bundles of fibers (the axons of neurons), that emanate from the brain and spinal cord, and branch repeatedly to innervate every part of the body. [5]
30 de oct. de 2023 · While the structure of a nerve is simple, their functions, innervations and nomenclature can be complex. In this article, we break down the different types of nerves, as well as their morphological features and functions.
