How the Ear Works

Few of the Different parts of the Ear


DEFINITION:

The ear is an organ of hearing and balance in humans and other vertebrates.


Ear Canal:

The ear canal, also called the external acoustic meatus, is a passage comprised of bone and skin leading to the eardrum.


Pinna (auricle):

The pinna – the part of the ear that we see on each side of our heads – is made of cartilage and soft tissue so that it keeps a particular shape but is also flexible.


Temporal Bone:

The temporal bone (the skull bone containing part of the ear canal, the middle ear, and the inner ear) can be fractured, usually by a blow to the head. A temporal bone fracture may cause hearing loss, bruising behind the ear, and bleeding from the ear.


Malleus:

The malleus (or hammer) is a hammer-shaped small bone of the middle ear which connects with the incus and is attached to the inner surface of the eardrum.
