<P> The cochlea / ˈkɒk. liə / ( Ancient Greek : κοχλίας , kōhlias , meaning spiral or snail shell ) is the auditory portion of the inner ear . It is a spiral - shaped cavity in the bony labyrinth , in humans making 2.5 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 fluid chambers in the coiled tapered tube of the cochlea . The name is derived from the Latin word for snail shell , which in turn is from the Greek κοχλίας kokhlias ( `` snail , screw '' ) , from κόχλος kokhlos ( `` spiral shell '' ) in reference to its coiled shape ; the cochlea is coiled in mammals with the exception of monotremes . </P>
