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.

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. Ear Canal The ear canal or external auditory meatus is approximately 1. The inner two-thirds of the ear canal is imbedded in the temporal bone.

Anatomy and physiology of the ear

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 human ear consists of three regions called the outer ear, middle ear, and inner ear. The oval window, also known as the fenestra ovalis, is a….

Hearing is one of the major senses and like vision is important for distant warning and communication. It can be used to alert, to communicate pleasure and fear.

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.

2 THE ANATOMY AND PHYSIOLOGY OF THE EAR AND HEARING

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. The human ear, like that of other mammals , contains sense organs that serve two quite different functions: that of hearing and that of postural equilibrium and coordination of head and eye movements. Anatomically, the ear has three distinguishable parts: the outer, middle, and 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.

Так начал обретать форму второй план. Стратмор вдруг увидел шанс выиграть на двух фронтах сразу, осуществить две мечты, а не одну. В шесть тридцать в то утро он позвонил Дэвиду Беккеру.
