The document describes the anatomy and function of the human ear. It details the three main parts of the ear: the outer, middle, and inner ear. The inner ear contains the vestibular system including the semicircular canals, and the cochlea which houses the organ of Corti that converts sound vibrations into electrical signals sent to the brain.
