Ears

Ears (/ɪərz/) are organs that are designed for hearing and balance. They are part of the auditory system and are located on the sides of the head.

Etymology

The word "ear" comes from the Old English word "ēare," which has cognates in various other Germanic languages.

Anatomy of the Ear

The ear can be divided into three parts: the outer ear, the middle ear, and the inner ear.

Outer Ear

The outer ear consists of the pinna (the visible part of the ear) and the ear canal. The pinna collects sound waves and directs them into the ear canal.

Middle Ear

The middle ear contains three small bones known as the ossicles: the malleus, the incus, and the stapes. These bones amplify the sound waves and send them to the inner ear.

Inner Ear

The inner ear contains the cochlea, which is responsible for hearing, and the vestibular system, which is responsible for balance.

Function of the Ear

The primary function of the ear is to convert sound waves into electrical signals that the brain can interpret as sound. The ear also plays a crucial role in maintaining balance.
