An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal. Since the outer ear is the only visible portion of the ear in most animals ...
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 ]
Cochlea. Semicircular canals. v. t. e. The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear ). The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ...
Brown is outer ear. Red is middle ear. Purple is inner ear. The auricula. Lateral surface. 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 ).
61734. Anatomical terminology. [ edit on Wikidata] The ear canal ( external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
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
e. In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and thence to the oval window in the fluid-filled cochlea.
