The vestibular duct or scala vestibuli is a
perilymph-filled cavity inside the
cochlea
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus (cochlea), modiolus. A core component of the cochlea is the organ of Cort ...
of the
inner ear
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the ...
that conducts sound vibrations to the
cochlear duct.
It is separated from the cochlear duct by
Reissner's membrane and extends from the
vestibule of the ear to the
helicotrema where it joins the
tympanic duct.
