The Cochlear Duct Contains All of the Following Except

Question

The cochlear duct contains all of the following except:
A)endolymph.
B)tectorial membrane.
C)perilymph.
D)organ of Corti.

Accepted Answer

The cochlear duct, or scala media, is filled with endolymph, not perilymph. Perilymph is found in the scala tympani and scala vestibuli, which are adjacent to the cochlear duct. The tectorial membrane and the organ of Corti are indeed found within the cochlear duct.
