Cochlea

Another section of a non-human cochlea shows this bony tube coiled into a spiral. The cochlear duct is centrally located within the cochlea, dividing it into a scala vestibuli, lying above the cochlear duct, and a scala tympani lying below. Scala vestibuli and scala tympani are continuous at the tip of the cochlea at the helicotrema. 40x
