The modiolus (plural: modioli) is part of the cochlea and is a conical-shaped structure that consists of spongy (porous) bone located in the center of the cochlea and contains the spiral ganglion.
The spiral lamina projects from the modiolus.
Abnormality of the modiolus results in sensorineural hearing loss.
History and etymology
The Latin word, "modiolus" means hub of a wheel, and is well-named, as in both the cochlea and at the angle of the mouth, the two modioli act as central foci around which other structures converge. Modiolus is a diminutive form of "modius" meaning a measure of grain (one sixth of a bushel) 2-4.
