CN VIII




El CN VIII, o nervio vestibulococlear, transmite información sensorial especial,
relacionada con el equilibrio y la audición, desde el oído interno hasta el cerebro.




El nervio vestibulococlear emerge lateralmente en el ángulo pontocerebeloso, que es
la unión entre la protuberancia, la médula y el cerebelo. Una vez que emerge del
ángulo pontocerebeloso, entra en el meato acústico interno, donde se separa en sus
dos ramas: el nervio coclear y el nervio vestibular.

, Nervio coclear → transmite información sobre la audición

Nervio vestibular → transmite información sobre los movimientos de la cabeza que
ayudan al equilibrio

VÍA DE LA INFORMACIÓN SENSORIAL DE LA VÍA AUDITIVA



Comienza en la cóclea
(tubo óseo que se enrolla
en espiral sobre sí mismo,
asemejándose a la forma
de una concha de
caracol).




Si desenrollamos esta estructura y observamos su interior en sección transversal,
hay tres cavidades llenas de líquido denominadas:

• Rampa vestibular (scala vestibuli)
Contiene perilinfa
Conectada al oído medio a través de la ventana oval
• Rampa coclear (cochlear duct)
Contiene endolinfa
Alberga el órgano de Corti (órgano de la audición que contiene nuestros
receptores auditivos o células ciliadas).
• Rampa timpánica (scala tympani)
Contiene perilinfa.
Conectada al oído medio a través de la ventana redonda
