The cochlea is part of the inner ear. It contains the organ of Corti, the stria vascularis, as well as endolymph and perilymph. The cochlea is the site of actual sound perception.
Anatomy
The bony cochlea consists of a spirally shaped tube, the cochlear canal (Canalis spiralis cochleae), which winds around a conically shaped central axis, the modiolus. A thin bony ridge, the lamina spiralis ossea, extends from the modiolus; together with the membranes attached to it, this divides the cochlear duct along its entire length into three tubes:
- Scala vestibuli (vestibular scala)
- Scala media (Ductus cochlearis)
- Scala tympani (tympanic scala)
