All About The Ear

Vibrations of air molecules moving through the air are standardized and translated into messages that the brain recognizes as blend by a complex organ--the spike heel. The atrial auricle has two important, but different, functions: hearing and perceptual experience the bodys equilibrium, or balance. The mechanisms for these processes are located within a travail quadriceps in the skulls temporal bone. Parts of the Ear and earreach The ear has ternary break dance sections:the satellite ear, the spirit ear, and the inner ear. Each section performs a specific function, think to either hearing or balance. The three parts of the outer(prenominal) ear are the auricle (also called the pinna), the outer auditory meatus (or ear canal), and the tympanic tissue layer (or eardrum). The pinna collects grueling waves from the air. It funnels them into a channellike tube, the impertinent auditory meatus . This is a curved corridor that leads to the tympanic membrane. The e ardrum separates the impertinent ear from the marrow ear. The middle ear is an irregular-shaped, air-filled space, some 0.75 inch (1.9 centimeters) high and 0.2 inch (0.5 centimeter) wide. A chainlike bear on of three tiny bones, the ossicles, spans the middle ear. When sound waves strike the outer surface of the eardrum, it vibrates. These vibrations are mechanically familial through the middle ear by the ossicles. The malleus, or hammer, is the prime(prenominal) ossicle to receive vibrations from the eardrum. It passes them to the minute ossicle--the incus, or anvil. The third ossicle--the stapes or stirrup--relays the vibrations to a membrane that covers the col into the inner ear. This opening is the move window. Like the eardrum, the round windows membrane transmits vibrations. It directs vibrations into the inner ear, where they enter a fluid that fills a structure called the cochlea. This is a coiled tube that resembles a...
