Scala Media

What is Scala Media?

The scala media is the middle section of the cochlea, which is a spiral-shaped structure in the inner ear. It is filled with a fluid called endolymph. The scala media is sandwiched between the scala vestibuli and the scala tympani.

What is the Scala Media of the Ear?

The scala media is the middle of the three fluid-filled chambers in the cochlea. It is separated from the scala vestibuli by Reissner’s membrane and from the scala tympani by the basilar membrane. The scala media contains endolymph, a fluid that is high in potassium and low in sodium.

What is the Function of the Scala Media?

The scala media is the site of hearing. When sound waves enter the ear, they cause the stapes, a small bone in the middle ear, to vibrate. This vibration is transmitted to the oval window, which is located at the base of the cochlea. The oval window then causes the fluid in the scala vestibuli to vibrate. This vibration is transmitted to the scala media, where it causes the basilar membrane to vibrate. The basilar membrane is covered with hair cells, which are sensory cells that send signals to the brain when they vibrate. These signals are interpreted by the brain as sound.

What is Found in the Scala Media?

The scala media contains endolymph, a fluid that is high in potassium and low in sodium. It also contains hair cells, which are sensory cells that send signals to the brain when they vibrate.
