The sensory organ for hearing and equilibrium in the human is the ear. The outer ear consists of the external pinna, as well as the auditory canal. Together, they collect sound waves and send them to the tympanic membrane. This membrane, known as the ear drum, separates the outer ear from the middle ear. In the middle ear, small bones (malleus, incus, and stapes) transmit amplified vibrations through the oval window to fluid within the vestibular canal. The round window of the tympanic canal serves as an escape valve for the pressure. The middle ear also opens into the Eustachian tube to aid in equalizing pressure between the middle ear and the atmosphere. The inner ear includes organs of equilibrium that sense the position of the body with respect to gravity. It consists of fluid-filled chambers, including the semicircular canals, as well as the bony cochlea that is involved in hearing. Hair cells in the organs of Corti in the cochlea are the receptors for hearing that generate action…
