The tube is protected by earwax, and by a set of fine hairs. These are used to moisten the ear, catch floating dust, and keep away small insects. The middle ear is called the drum of the ear. Between the middle ear and outer ear is a thin skin Called the membrane of the drum. It is very delicate, and if it is once broken, it cannot be repaired, and deafness will follow. In the drum of the ear are three little bones, the smallest in the body. An air passage leads from the throat to the drum of the ear. The inner ear is made up of a number of winding passages cut through the skull to the brain. These passages are lined with a thin skin on which the nerve of hearing is spread out. Inside of this skin is a watery fluid in which float tiny grains of sand. Waves of sound are collected by the outer ear and pass to the membrane of the drum, causing it to vibrate. When this membrane vibrates, it causes the three little bones in the middle ear to vibrate. This causes the fluid in the inner ear to wash the tiny grains of sand against the nerve of hearing; the nerve of hearing carries this impression to the brain, and we know that we hear a sound.
