Modiolus (cochlea)
Conical shaped central axis in the cochlea
From Wikipedia, the free encyclopedia
The modiolus is a conical shaped central axis in the cochlea. The modiolus consists of spongy bone and the cochlea turns approximately 2.75 times around the central axis in humans.[1] The cochlear nerve, as well as spiral ganglion is situated inside it. The cochlear nerve conducts impulses from the receptors located within the cochlea.
