Abstract
The cochlea, the auditory portion of the inner ear, is coiled upon itself around the modiolus like a snail shell and makes 2½ to 2¾ turns. The basal turn (the largest in diameter) is the medial wall of the middle ear, which is a domelike prominence called the promontory. The actual starting point of the basal turn which is located within the hook region near the round window could not be shown on the outer surface of the cochlea (Erixon et al. 2009). There are three compartments within the cochlea. Two of them, the scala vestibuli (associated with the vestibular window) and the scala tympani (associated with the cochlear window), contain perilymph. The third, the cochlear duct, contains endolymph. The organ of Corti, the neural end organ of hearing, rests on the basilar membrane, which connects the medial spiral lamina and lateral spiral ligament.
