El sistema nervioso periférico está constituido por todos los nervios de tu cuerpo, excepto los del cerebro y la médula espinal. Actúa como un transmisor de la comunicación entre tu cerebro y tus extremidades.

En ese escaso tiempo, tu cerebro le indica a los músculos del brazo y la mano retirar inmediatamente tu dedo de la hornalla.
