The ear has three parts, the outer ear or oracle, the middle ear and the inner ear. The oracle, the visible part of the ear, collects sound waves and directs them to the auditory canal. The auditory or ear canal is lined with silia and seruminous glands. The ear wax from the seruminous gland and the silia protect the ear from entry by four in matter. The thin, tempatic membrane separates the outer ear from the middle ear. The surface causes it to vibrate. The three tiny bones of the middle ear are the hammer, or malleus, anvil, or incus, and stapes or stirrup. These bones pick up the vibrations from the tempatic membrane and transmit them to the inner ear. The oestation tube of the middle ear opens into the pharynx and permits air pressure to equalize between the ear and the outside ear. The inner ear is maize-like, consisting of bony and membranous structures surrounded by fluid. The semi-circular canals are fluid-filled bony loops that help maintain our body's balance. The cochlea is a fluid-filled, snail-shaped structure that houses the organ of corti, the true organ of hearing, the fluid aids in the transmission of the vibrations. The organ of corti changes the vibrations into nerve impulses that are picked up by the auditory nerve. Sound waves are collected by the oracle or outer ear and sent to the auditory canal, tempatic membrane, ear bones, and then to the cochlea, where the vibrations are changed by the organ of corti. To nerve impulses and transmitted by the auditory or cochlear nerve to the temporal lobe of the brain for interpretation.
