The inner ear consists of the cochlea and several non-auditory structures. The cochlea has three fluid-filled sections (i.e. the scala media, scala tympani and scala vestibuli), and supports a fluid wave driven by pressure across the basilar membrane separating two of the sections.
In humans, the ear is described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the auricle and the ear canal . Since the outer ear is the only visible portion of the ear, the word "ear" often refers to the external part (auricle) alone. [ 1 ]
The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates , the inner ear is mainly responsible for sound detection and balance. [ 1 ] In mammals , it consists of the bony labyrinth , a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [ 2 ]
The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [1] It gathers sound energy and focuses it on the eardrum ( tympanic membrane ).

Structural diagram of the cochlea showing how fluid pushed in at the oval window moves, deflects the cochlear partition, and bulges back out at the round window. The cochlea ( pl. : cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window ) to the apex (the top or ...
The diagram shows the shape and location of most of these components: antihelix forms a 'Y' shape where the upper parts are: Superior crus (to the left of the fossa triangularis in the diagram) Inferior crus (to the right of the fossa triangularis in the diagram) Antitragus is below the tragus; Aperture is the entrance to the ear canal
The vestibule is the central part of the bony labyrinth in the inner ear, and is situated medial to the eardrum, behind the cochlea, and in front of the three semicircular canals. [1] The name comes from the Latin vestibulum, literally an entrance hall.
