stirrup; last of the tree auditory ossicles of the middle ear | stapes |
tube connectig the middle ear to the pharynx (throat) | eustachian tube or auditory tube |
projection of the temporal bone located behind the ear containing air cells that connect to the middle ear (masto=breast) | mastoid process |
membrane that covers the opening between the middle ear and inner ear | oval window |
structures and liquids that relay sound waves to the auditory nerve fibers on a path to the brain for interpretation of sound | inner ear |
maze; inner ear consisting of bony and membranous labyrinths | labyrinth |
coiled tubular structure of the inner ear that contains the organ of Corti | cochlea |
fluid that fills the bony labyrinth of the ear | perilymph |
fluid within the cochlear duct of the inner ear (labyrinth) | endolymph |
organ located in the cochlea that contains receptors (hair cells) that receive vibrations and generate nerve impulses for hearing | organ of Corti |

inflammation of the middle ear | otiis media |
inflammation of the middle ear from changes in atmospheric pressure; often occurs in frequent air travel | aerotitis media |
hardening of the bony tissue in the ear | otosclerosis |
inflammation of the mastoid process; most commonly seen as a result of the spread of inflammation and infection in otitis media | mastoiditis |
