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….
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 outer ear consists of the visible portion called the auricle , or pinna, which projects from the side of the head, and the short external auditory canal , the inner end of which is closed by the tympanic membrane , commonly called the eardrum. The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone.
Anatomy and Physiology of the Ear
Ears are responsible for both hearing and maintaining the balance of the body. The ears are composed of. This structure is peculiar to terrestrial organisms. Outer ear is involved in collection, amplification and transmission of the sounds. It is composed of a pinna, an external auditory canal and an ear drum. Pinna is a cartilage tissue that has a distinct shape. It collects the sound waves and determines their source and amplifies them.

The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance. The best way to describe the functioning of the ear is to describe the path which the sound waves take on their way through the ear.

У дверцы лифта есть код, - злорадно сказала Сьюзан. - Ну и проблема! - засмеялся Хейл. - Думаю, коммандер мне его откроет. Разве не так, коммандер. - Ни в коем случае! - отрезал Стратмор. Хейл вскипел: - Послушайте меня, старина.
