Anatomically, the ear has three distinguishable parts: the outer, middle, and inner ear. The ear canal is the opening through which sound waves enter the middle ear. In mammals, the ear is usually described as having three parts—the outer ear, the middle ear and the inner ear. Content Guidelines 2. The sensory hairs project from the outer ends of the hair cells into the scala media, while from the inner end of the cells nerve fibres arise, which unite to form the cochlear nerve.
