Basilar membrane

Definition

The basilar membrane is a key structure within the cochlea of the inner ear that plays a crucial role in the process of hearing by supporting the organ of Corti, which contains hair cells that convert sound vibrations into neural signals. It varies in width and stiffness along its length, properties that are essential for it to decode sounds of different frequencies.

Cochlea:

The spiral-shaped cavity in the inner ear containing the organ of Corti and basilar membrane, responsible for converting sound vibrations into electrical signals.

Organ of Corti:

A structure located on the basilar membrane that contains hair cells, which are essential for detecting sound vibrations and turning them into nerve impulses.

Hair Cells:

Sensory cells located within the organ of Corti on the basilar membrane, acting as receptors that convert mechanical sound vibrations into electrical signals sent to the brain
