SENSE OF HEARING AND BALANCE ANATOMY

Hearing involves structures that are formed in the inner ear, the middle ear, and the outer ear. The inner ear contains structures specifically related to balance and equilibrium.

During embryonic development, the inner ear begins developing at age 4 weeks (gestational) and is complete at 32 weeks (gestational.) The ear is an organ designed to serve two purposes, hearing and establishing and maintaining equilibrium.

The ear houses two different types of receptors, one which is stimulated by sound waves and the other which responds to the stimulation delivered by head movement.

Both types of receptors send their impulses through the vestibulocochlear nerve to the brain, where the information is then interpreted.
