cochlear duct

The cochlear duct is almost as complex on its own as the ear itself.

Instead, it forms a blind-ended tube, also called the cochlear duct.

The basilar crest lies within the cochlear duct in the inner ear.

This central column is called the scala media, or cochlear duct.

Part of the saccule will eventually give rise and connect to the cochlear duct.

The saccule gives rise to the cochlear duct, which is involved in the special sense hearing.

The basilar membrane separates the cochlear duct from the scala tympani, a cavity within the cochlear labyrinth.

The lateral wall of the cochlear duct is formed by the spiral ligament and the stria vascularis, which produces the endolymph.

The vestibular wall will separate the cochlear duct from the perilymphatic scala vestibuli, a cavity inside the cochlea.

The cochlear duct is bounded on three sides by the basilar membrane, the stria vascularis, and Reissner's membrane.

Strikingly, one section, called the cochlear duct or scala media, contains endolymph, a fluid similar in composition to the intracellular fluid found inside cells.

The fluid found in these two cochlear chambers is perilymph, while scala media, or the cochlear duct, is filled with endolymph.

The organ of Corti sits inside the cochlear duct, between the scala vestibuli and the scala tympani.

The saccule opens into the cochlear duct, through the canalis reuniens, and the semicircular ducts communicate with the utricle.

The hair cells develop from the lateral and medial ridges of the cochlear duct, which together with the tectorial membrane make up the organ of Corti.

The RM separates endolymph in the cochlear duct from underlying corticolymph and perilymph of the scala tympani.

A spiral ligament and a cartilaginous process called the modiolus connect and support the cochlear duct to the rest of the cartilaginous structures that surround it.

Hair cells in the cochlear duct, specifically the organ of Corti, are deflected as waves of fluid and membrane motion travel through the chambers of the cochlea.

A set of membranes called the vestibular membrane and the basilar membrane separate the cochlear duct from the scala vestibule and the scala tympani.

As a result of this increase in length, the basilar membrane and papilla are both extended, with the latter developing into the organ of Corti, while the lagena is now called the cochlear duct.

Beginning in the fifth week of development, the auditory vesicle also gives rise to the cochlear duct, which contains the spiral organ of Corti and the endolymph that accumulates in the membranous labyrinth.

Cochlear duct: fluid waves in the endolymph of the cochlear duct stimulate the receptor cells, which in turn translate their movement into nerve impulses that the brain perceives as sound.

One from the middle part forms the ductus and saccus endolymphaticus, another from the anterior end gradually elongates, and, forming a tube coiled on itself, becomes the cochlear duct, the vestibular extremity of which is subsequently constricted to form the canalis reuniens.

The cochlear duct (or scala media) is an endolymph filled cavity inside the cochlea, located in between the scala tympani and the scala vestibuli, separated by the basilar membrane and Reissner's membrane (the vestibular membrane) respectively.
