Get vibrations from ear drum and bring to oval window that leads into the fluid of the inner ear which excites hearing receptors. Each plays a role in hearing and one a role in maintaining balance.

The vestibular system is the sensory apparatus of the inner ear that helps the body maintain its postural equilibrium. The pinna and external auditory canal form the outer ear which is separated from the middle ear by the tympanic membrane. The outer ear is composed of the pinna or ear lobe and the external auditory canal.

The information furnished by the vestibular system is also essential for coordinating the position of the head and the movement of the eyes. For the most part they are inaccessible to direct inspection with the exception of the ear canal and ear drum tympanic membrane. The middle ear houses three ossicles the malleus incus and stapes and is connected to the back of the nose by the eustachian tube.
