EAR

Ears are the organs of hearing. The ear has three parts: outer ear, middle ear, and inner ear. The auricle (pinna) and outer ear canal, which delivers sound to the middle ear, make up the outer ear, the part we see. Within the outer ear wax-producing glands and hairs that protect the middle ear are located. The function of the middle ear is to deliver sound to the inner ear, where it is processed into a signal that the brain recognizes. The middle ear is a small cavity, with the eardrum on one side and the entrance to the inner ear on the other side. Within the

Ear

ear there are three small bones (the ossicles) known as the malleus (hammer), incus (anvil), and stapes (stirrup). These bones conduct sound vibrations into the inner ear. The malleus is attached to the lining of the eardrum, the incus is attached to the malleus, and the stapes links the incus to the oval window (the opening to the inner ear).

The middle ear is connected by a narrow channel (the Eustachian tube) to the throat. Ordinarily, the Eustachian tube is closed, but when the person swallows or yawns, it opens to allow an exchange of air, thus equalizing the air pressure within the middle ear and the air pressure outside.

The inner ear contains the most important parts of the hearing mechanism. They are two chambers called the vestibular labyrinth and the cochlea. Tiny hairs line the curves of the cochlea. Both the labyrinth and the cochlea are filled with fluid. When sound waves from the world outside strike the eardrum, it vibrates. These vibrations from the eardrum pass through the bones of the middle ear and into the inner ear through the oval window. Then they disseminate into the cochlea, where they are converted into electrical impulses and are transmitted to the brain by the auditory nerve.
