, Fisiología
El LCR es un medio nutriente del sistema nervioso central y es vía de excreción para
productos metabólicos del sistema nervioso central.
El LCR se encuentra en el espacio subaracnoideo, entre la piamadre y la aracnoides.
, Fisiología
El líquido formado en los ventrículos cerebrales laterales pasa al tercer y cuarto ventrículo,
sigue hasta la cisterna magna, atraviesa los agujeros de Luschka y Magendie y penetra
dentro del espacio subaracnoideo, donde circula por los hemisferios cerebrales, mientras
que una pequeña cantidad circula hacia abajo por la médula espinal.
, LCR se forma: en los plexos coroideos
LCR se reabsorbe: vellosidades aracnoideas
Funciones del LCR:
1) Soporte y protección del SN
2) Transporte de sustancias (hormonas, neurotransmisores,…)
3) Vehículo para la excrección de productos de la actividad del metabolismo cerebral
4) Controlar las características químicas del entorno del SNC
