Parts of the Ear. The ear plays an influential part in the sensory system. This organ is a key portion of the auditory system, which translates sound waves into a signal that the brain can interpret. In addition to helping the body take in auditory messages, the ear helps to maintain a proper head position. The fluid in the ear also helps the body maintain a sense of balance so the body can maintain proper posture and coordination. There are three major portions of the ear, the outer, middle and inner ear. Each contains several parts that are essential to the overall function of the ear. Outer Ear. Description and Function. The outer ear is the portion of the ear that sits atop the skull, which is made of flesh and cartilage.

The cochlear labyrinth controls hearing, primarily at low frequencies whereas the vesibular labyrinth controls balance. When inflamed, it can cause various parts of the inner ear to become swollen and irritated, causing disruptions in the flow of sound waves through the ear, creating a loss of balance and hearing.
