What are the structures of the cochlea?
When the cochlea is stretched out and cut, we can see the 3 ducts and all the structures.
The cochlea consists of 3 ducts: Vestibular (top), Cochlear (middle), and Tympanic duct (bottom).
The information enters through the oval window and travels through the vestibular duct and comes back around through the tympanic duct and exists through the round window. A membrane outside of the round window absorbs the impact.
The cochlea duct is in between the vestibular and tympanic duct. Inside of the cochlea duct lies the organ of corti and it runs through the entire cochlea. As information travels around the vestibular and tympanic duct, the cranial nerves of the tectorial membrane (top) and the hairs of the organ of corti (bottom) connect and pass electrical impulses down the auditory nerves heading to the temporal lobes.
The organ of corti sits on the Basilar membrane and running over head lies the tectorial membrane.
