The ear has three main parts - the external ear, middle ear, and inner ear. The external and middle ear are primarily concerned with transmitting sound, while the inner ear is responsible for both hearing and balance functions. The external ear has two parts, a length and curvature, and is supplied by nerves. The middle ear contains three air-filled parts. The inner ear contains the organs for hearing and balance.
