The inner ear contains the labyrinth, which help us keep our balance. The cochlea, a part of the labyrinth, is a snail-shaped organ that converts sound vibrations from the middle ear into electrical signals. The auditory nerve carries these signals from the cochlea to the brain.

Ear, Inner: The essential part of the hearing organ consists of two labyrinthine compartments: the bony labyrinthine and the membranous labyrinth. The bony labyrinth is a complex of three interconnecting cavities or spaces (Cochlea; Vestibular Labyrinth; and Semicircular Canals) in the Temporal Bone. Within the bony labyrinth lies the membranous labyrinth which is a complex of sacs and tubules (Cochlear Duct; Saccule And Utricle; and Semicircular Ducts) forming a continuous space enclosed by Epithelium and connective tissue. These spaces are filled with Labyrinthine Fluids of various compositions.3
