Cochlea
A spiral shell; kokhlias = snailThe cochlea is the spiral chamber of bone in the inner ear which contains the cochlear duct, redolent of a snail’s shell. The cochlea receives and helps to interpret sound vibrations in the process of hearing.
As anatomists came across membranes or bony and cartilaginous prominences during their dissections, they would name them after a wide range of animals which the structures resembled.
