Describe the Following Otolaryngology Flashcards

Study of the ears, nose, and throat. The organs that contain the receptors for hearing and smelling are located in the ears and nose. The sense of hearing occurs through the mechanical action of the ear and its three anatomic diversions: the external, middle, and inner ear.

The organs of both hearing and balance

Structurally designed to collect sound waves and to direct them inward. Consists of the auricle (pinna), external auditory canal, and tympanic membrane (eardrum).

Aka pinna, the stationary outermost part of the ear, the trumpet shaped flap of elastic cartilage covered with thick skin.

Connected to the auricle (outermost structure of the ear), contains the ceruminous glands that emit a yellowish-brown substance called cerumen (ear wax) which protects and lubricates the ear.

Sound waves that travel through the external auditory canal strike the eardrum, which cause vibrations. This energy is transferred to the three tiny bones of the middle ear (malleus, incus, and stapes).

Malleus (hammer), incus (anvil), stapes (tiny stirrup). Named for their characteristic shapes.

An auditory tube that connects the middle ear to the nasopharynx and helps maintain equal air pressure on both sides of the eardrum.

The labyrinth (maze) of the ear, is a complex system of communicating chambers and tubes that contain receptors for hearing and balance.

Seperates the middle and inner ear.

Contains a basilar membrane. Contains special auditory fluids, that aids the transmission of sound vibrations.

Auricle > External Auditory Canal > Tympanic Membrane > 3 inner ear bones > Oval window > Cochlea

Ear drum, transfers vibrations from sound waves to the three inner ear bones (malleus, incus, stapes).

Air enters and leaves the body through it, made up of bone and cartilage covered with skin.

Naris, the entrance to the nose.
