The inner ear (aka labyrinth) is the deepest part of the ear and plays an essential role in hearing and balance. It contains the cochlea, a snail-shaped bony structure filled with fluid. As sound waves travel from the outer to the inner ear, they create waves in the inner ear fluid of the cochlea.

The inner ear is the innermost part of the ear, responsible for both hearing and balance. It consists of two major structures: the cochlea, which is involved in hearing, and the vestibular system (including the semicircular canals, utricle, and saccule), which is responsible for maintaining balance and spatial orientation.

Your inner ear contains two main parts: the cochlea and the semicircular canals. Your cochlea is the hearing organ. This snail-shaped structure contains two fluid-filled chambers lined with tiny hairs. When sound enters, the fluid inside of your cochlea causes the tiny hairs to vibrate, sending electrical impulses to your brain.

The inner ear is at the end of the ear canals, resting in the temporal bone. It consists of the cochlea, semicircular canals, and vestibule and is responsible for hearing, balance, and equilibrium. The cochlea converts sound into nerve impulses that the brain processes to interpret sound.

There are two main sections within the inner ear: the bony labyrinth and the membranous labyrinth. The cochlea, the hearing organ, is located inside the inner ear. The snail-like cochlea is made up of three fluid-filled chambers that spiral around a bony core, which contains a central channel called the cochlear duct.
