The scala vestibuli is also known as the vestibular duct.

What is the scala vestibuli?

The scala vestibuli is one of the three fluid-filled chambers of the cochlea, a spiral-shaped structure in the inner ear. It is located above the basilar membrane and contains perilymph, a fluid that is similar to cerebrospinal fluid.

What is the scala vestibuli attached to?

The scala vestibuli is attached to the oval window, a membrane that separates the middle ear from the inner ear. 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 scala vestibuli, which is located above the basilar membrane.

What is the scala vestibuli and scala tympani?

The scala vestibuli and scala tympani are two of the three fluid-filled chambers of the cochlea. The third chamber is the cochlear duct, which contains endolymph. The scala vestibuli and scala tympani are connected at the helicotrema, a small opening at the apex of the cochlea.

What is the main function of the scala vestibuli?

The main function of the scala vestibuli is to transmit sound waves to the scala tympani. When sound waves enter the ear, they cause the scala vestibuli to move. This movement of fluid is transmitted to the scala tympani, which causes the fluid in the scala tympani to move as well. This movement of fluid bends the basilar membrane, which stimulates the hair cells in the cochlea. The hair cells then send signals to the brain, which interprets them as sound.
