scala media

They are in direct contact with the endolymph of the Scala media.

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

The marginal cells are involved primarily in K transport and line the endolymphatic space of the scala media.

The basilar membrane supports the organ of Corti, which sits within the scala media.

Scala media houses the organ of Corti.

The scala media contains endolymph.

It's also clearer if we treat two of the tubes, the scala vestibuli and the scala media, as one chamber.

It produces endolymph for the scala media, one of the three fluid-filled compartments of the cochlea.

It separates scala media from scala vestibuli.

Instead, the influx of positive ions from the endolymph in Scala media depolarizes the cell, resulting in a receptor potential.

Reissner's membrane is composed of two cell layers and separates the scala media from the scala vestibuli.

The organ of Corti forms a ribbon of sensory epithelium which runs lengthwise down the cochlea's entire scala media.

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

Within the cochlea are three fluid filled spaces: the scala tympani, the scala vestibuli and the scala media.

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

Scala vestibuli is a perilymph-filled cavity inside the cochlea of the inner ear that conducts sound vibrations to the scala media.

A cross section of the cochlea will reveal an anatomical structure with three main chambers (scala vestibuli, scala media, and scala tympani).

As the cochlear duct's mesenchyme begins to differentiate, three cavities are formed: the scala vestibule, the scala tympani and the scala media.

It is separated from the scala media by Reissner's membrane and extends from the vestibule of the ear to the helicotrema where it joins scala tympani.

The perilymph in scala vestibuli and the endolymph in scala media act mechanically as a single duct, being kept apart only by the very thin Reissner's membrane.

The vibrations of the endolymph in the scala media displace the basilar membrane in a pattern that peaks a distance from the oval window depending upon the soundwave frequency.

This movement is conveyed to the organ of Corti inside the scala media, composed of hair cells attached to the basilar membrane and their stereocilia embedded in the tectorial membrane.

They derive their name from the tufts of stereocilia that protrude from the apical surface of the cell, a structure known as the hair bundle, into the scala media, a fluid-filled tube within the cochlea.

The scala vestibuli and scala media are separated by Reissner's Membrane whereas the scala media and scala tympani are divided by the basilar membrane.

The basilar membrane within the cochlea of the inner ear is a stiff structural element that separates two liquid-filled tubes that run along the coil of the cochlea, the scala media and the scala tympani (see figure).
