Question

Choose between the two options to answer the question specified in the brackets for the following.

Perilymph or endolymph (Which one surrounds the organ of Corti?)

Answer 1

The inner ear:

1. The inner ear is made up of two parts: the bony and membranous labyrinth, which is made up of fluid-filled chambers within the temporal bone of the skull.
2. The membrane labyrinth is located inside the bony labyrinth and is bordered by a fluid called perilymph, whereas the membranous labyrinth is filled with endolymph.
3. The cochlea is the coiled section of the labyrinth, and the cochlear duct is filled with endolymph.
4. The Corti organ is located at the bottom of the cochlear duct.
5. As a result, endolymph surrounds the Corti organ.
