The following is a discussion of one of the tools, the human senses, namely hearing aids, hearing, hearing and function, the function of the ear, according to the ear, the function of the screw of the ear function of the tympanic membrane, the function of the cochlea, ear anatomy and ear along function portions.
Parts of the ear
The human ear is hearing and balance. As in the following figure is the ear three parts as follows. 1) The external ear consists of the ear canal, the ear of the sebaceous glands and the tympanic membrane. to detect the function of the noise of the external ear or noise. 2) The middle ear (tympanic cavity) in the form of a small cavity filled with air, is located in the bone and the walls are covered with epithelial cells. middle ear ossicles are namely the hammer bone, anvil and stirrup. The middle ear is connected to the throat through the Eustachian canal. Channel function Eustace This air pressure in the middle ear equalizes atmospheric pressure. 3) The inner ear, berlekuklekuk with a channel section consists of several parts, namely, elliptical leaves, circular opening, the three semicircular canals and cochlea (cochlear) in which he endolymph fluid. the function of the inner ear for receiving a stimulus.
Parts of the ear
The consultation process can be illustrated by the following chart. The sound waves vibrate the air and picked up by the ear and reflect sound waves in the ear canal, and then click the slide eardrum.Vibration ossicles ellipse transmitted so that the lymph fluid in the cochlea to vibrate. This oscillation causes the hair cells to vibrate so that the ends of the auditory nerve excited. The nerve impulse is then the size is passed through the auditory nerve to the brain. Stimulation is then translated by sound or voice. In addition to a sense of hearing, hearing also acts as a sense of balance. The provision of a sense of imbalance in the bottle, the base of the three semicircular canals swells. In the ampoule contains hair cells that are sensitive to the gravity. When he shook his head, change the direction of the hair cells. These changes are received by nerve cells in the brain then accepted. As a result, you will be aware of a position of the head and body. The ears can be hearing loss of the ear is called. There are two types of hearing loss is as follows. 1) Accumulated deafness due to the interruption of the transmission of sound in the cochlea as dirt, pus that occur in inflammation of the middle ear causes damage to the ossicles. 2) nervous Tuli, if the cochlea or auditory nerve damage.
