The ears are organs that provide two main functions — hearing and balance — that depend on specialized receptors called hair cells. Sound waves enter through the outer ear, move into the middle ear, and finally reach the inner ear and its intricate network of nerves, bones, canals, and cells. There are three bones located in the middle ear: the incus, the malleus and the stapes. Collectively, all three bones comprise the ossicles. The malleus is the outermost and largest of the three small bones in the middle ear, and reaches an average length of about eight millimeters in the….

The Inner Ear

External auditory canal or tube. This is the tube that connects the outer ear to the inside or middle ear. Tympanic membrane eardrum. The tympanic membrane divides the external ear from the middle ear. Three small bones that are connected and transmit the sound waves to the inner ear.

The ear is a complex and delicate organ. It collects sound waves so you can hear the world around you. The ear also has a second function—it helps you keep your balance. Your ear can be divided into 3 main parts. These are the outer ear, the middle ear, and the inner ear.

The ear can be divided into three parts: the outer ear , middle ear and inner ear. The inner ear is the innermost part of the ear, and houses the vestibulocochlear organs. It has two main functions:. In this article, we shall look at the anatomy of the inner ear — its position, structure, and neurovascular supply. The inner ear is located within the petrous part of the temporal bone. The inner ear has two main components — the bony labyrinth and membranous labyrinth. The inner ear has two openings into the middle ear, both covered by membranes.

NCBI Bookshelf. The human ear is the organ of hearing and equilibrium. It detects and analyzes sound by the mechanism of transduction, which is the process of converting sound waves into electrochemical impulses. Audition cannot take place adequately if the anatomy is abnormal.

Anatomy of the Ear

The following article is written to provide a general understanding of the structures within the auditory system and how they function. The auditory system is comprised of three components; the outer, middle, and inner ear, all of which work together to transfer sounds from the environment to the brain. Pinna The pinna or auricle is a concave cartilaginous structure, which collects and directs sound waves traveling in air into the ear canal or external auditory meatus.

Please consult the latest official manual style if you have any questions regarding the format accuracy. Mechanical events resulting from sound, gravitational forces, and rotational acceleration are detected by the cochlea and vestibular organs within the inner ear. Sound is a mechanical vibration eg, as produced by a vibrating piano string. This vibration sets up small oscillations of air molecules that, in turn, cause adjacent molecules to oscillate as the sound propagates away from its source. Sound is called a pressure wave because when the molecules of air come closer, the pressure increases compression ; as they move further apart, the pressure decreases rarefaction. A sound is characterized by its frequency and intensity.

С каждым мгновением появлялась новая линия, а за ней - следующая. - Они повсюду! - крикнула Соши. - Присоединяются зарубежные налетчики! - крикнул один из техников.  - Уже обо всем пронюхали. Сьюзан отвернулась от экрана ВР к боковому монитору. На нем бесконечно повторялась видеозапись убийства Танкадо. И всякий раз Танкадо хватался за грудь, падал и с выражение ужаса на лице навязывал кольцо ничего не подозревающим туристам.

В перерывах между сигналами Сьюзан выкрикнула: - Ты - Северная Дакота, Энсей Танкадо передал тебе копию ключа. Он нужен мне немедленно.

 Проклятие! - выругался он, потянувшись к телефону сквозь сплетение проводов.  - Джабба слушает. - Джабба, это Мидж. Он просиял.

Это значит - Кто будет охранять охранников?.

Кто-то рядом с ним попытался его приподнять. Он потянулся к голосу. Или это его подвинули.

    Human ear , organ of hearing and equilibrium that detects and analyzes sound by transduction or the conversion of sound waves into electrochemical impulses and maintains the sense of balance equilibrium.
