Answer:
The Outer Ear
The outer ear includes:
auricle (cartilage covered by skin placed on opposite sides of the head)
auditory canal (also called the ear canal)
eardrum outer layer (also called the tympanic membrane)
The outer part of the ear collects sound. Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum.
The Middle Ear
The middle ear includes:
eardrum
cavity (also called the tympanic cavity)
ossicles (3 tiny bones that are attached)
malleus (or hammer) - long handle attached to the eardrum
incus (or anvil) - the bridge bone between the malleus and the stapes
stapes (or stirrup) - the footplate; the smallest bone in the body
The Inner Ear
The inner ear includes:
oval window - connects the middle ear with the inner ear
semicircular ducts - filled with fluid; attached to cochlea and nerves; send information on balance and head position to the brain
cochlea - spiral-shaped organ of hearing; transforms sound into signals that get sent to the brain
auditory tube - drains fluid from the middle ear into the throat behind the nose
