  • Système nerveux
CONT

Les différentes vitesses de conduction des deux types de fibres nerveuses nociceptives (A-delta et C) expliquent la façon particulière dont on ressent la douleur lorsqu'on se blesse : d'abord une douleur aiguë, vive et précise qui fait place quelques secondes plus tard à une douleur plus diffuse et plus sourde.

CONT

Les fibres nociceptives rejoignent la moelle par les racines dorsales puis, par les voies ascendantes médullaires, le message douloureux est transmis aux centres supérieurs.
