Descriptor English: Basilar Membrane
Descriptor Spanish: Membrana Basilar
Descriptor membrana basilar
Scope note: Membrana basal de la cóclea, que sostiene las células ciliadas del ÓRGANO DE CORTI, y está constituida por fibrillas similares a queratina. Se extiende desde la LÁMINA ESPIRAL hasta la cresta basilar. El movimiento del líquido en la cóclea, inducido por el sonido, provoca el desplazamiento de la membrana basilar y la subsiguiente estimulación de las células ciliadas adheridas a la misma, lo que transforma la señal mecánica en actividad neuronal.

Scope note: A basement membrane in the cochlea that supports the hair cells of the ORGAN OF CORTI, consisting keratin-like fibrils. It stretches from the SPIRAL LAMINA to the basilar crest. The movement of fluid in the cochlea, induced by sound, causes displacement of the basilar membrane and subsequent stimulation of the attached hair cells which transform the mechanical signal into neural activity.
