Anatomical terminology []

The cochlear cupula is a structure in the cochlea. It is the apex of the cochlea. The bony canal of the cochlea takes two and three-quarter turns around the modiolus. The modiolus is about 30 mm. in length, and diminishes gradually in diameter from the base to the summit, where it terminates in the cupula.
