The ear is the organ of hearing and balance. It consists of three parts: outer ear, middle and inner. The first includes the ear and ear canal. The second, which is in the call box eardrum has an external face formed by the eardrum and communicates with the nose and throat through the eustachian tube. Inside the middle ear is a chain composed of three small bones and mobile (hammer, anvil and stirrup) that cross and link the eardrum to the inner ear. The inner ear or labyrinth contains the organ of balance and hearing defects. Located within the temporal bone is composed of the bony cochlea, the vestibule and three semicircular canals, which contain a substance called endolymph. The sound waves reach the eardrum through the ear canal, and there produces a vibration that is transmitted to the middle ear and it moves to the inner ear fluid. The movement of the endolymph stimulates hair cells that form the organ of Corti, which in turn transmit signals to the auditory nerve and thence to the brain.
