Ears and Hearing. The ear is a group of sensory organs in the head that collaborate to produce the sense of hearing. Together these organs perform the amazing function of converting sound waves in air into electrical signals to transmit to the brain. The ear also contains several special structures that produce the bodyâs sense of equilibrium, or balance. Three major regions make up the ear: the outer ear, middle ear, and inner ear.
The anatomy of the ear can be a little confusing, especially since the ear is responsible not only for hearing, but also for balance. There are three components to the ear: the outer ear, the middle ear and the inner ear. All three are involved in hearing but only the inner ear is responsible for balance.The outer ear is composed of the pinna, or ear lobe, and the external auditory canal.Both structures funnel sound waves towards the ear drum or tympanic membrane allowing it to vibrate. The pinna is also responsible for protecting the ear drum from damage. Modified sweat glands in the ear canal form ear wax.he anatomy of the ear can be a little confusing, especially since the ear is responsible not only for hearing, but also for balance.
