The Cochlear Duct Lies Between Which Two Structures

Question

The cochlear duct lies between which two structures?
A) utricle and saccule
B) vestibule and semicircular canals
C) basilar and tectorial membranes
D) scala vestibuli and scala tympani
E) ganglion cells and the cochlear nerve

Accepted Answer

The cochlear duct is part of the cochlea and lies between the scala vestibuli and scala tympani. The basilar membrane is located within the cochlear duct and is important in the process of sound transduction. The utricle and saccule, vestibule and semicircular canals, and ganglion cells and the cochlear nerve are all located within the inner ear, but are not directly associated with the cochlear duct. The tectorial membrane is located above the hair cells in the cochlea, but is not part of the cochlear duct itself.
