thumb|3D model of cochlea and semicircular canals The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. A core component of the cochlea is the organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea.

thumb|3D model of cochlea and semicircular canals The cochlea is the part of the inner ear involved in hearing.

A core component of the cochlea is the organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea.

==Etymology== The name 'cochlea' is derived from the Latin word for snail shell, which in turn is from the Ancient Greek κοχλίας kokhlias ("snail, screw"), and from κόχλος kokhlos ("spiral shell") in reference to its coiled shape; the cochlea is coiled in mammals with the exception of monotremes.
