3 layers
46
What are the 3 layers of the tympanic membrane?
Lateral surface, middle layer, and medial surface
47
Composed of a thin layer of skin that is continuous with the EAC. The epithelial layer
The lateral surface of the tympanic membrane
48
Composed of fibrous connective tissues. Helps the TM vibrate in response to acoustic stimuli.
The middle layer of the tympanic membrane
49
Formed by the mucus membrane which lines the middle ear
the medial surface of the tympanic membrane
50
the fibrocartilaginous ring at the edges of the tympanic membrane
tympanic annulus

opening in the attic or roof of the middle ear
aditus

minute air-filled chamber medial to the TM
Tympanum or tympanic cavity-
59
The roof of the middle ear. Formed by the mastoid portion of the temporal bone
superior wall
60
the floor of the middle ear cavity. Formed by the tympanic plate. Separates the middle ear cavity from the jugular bulb

What is the promontory?
the bulge on the medial wall of the middle ear cavity
65
What nerve passes through the middle ear?
facial nerve
66
What is another name for the anterior wall?
The carotid wall because carotid artery is right in front of it

What is another name for the eustachian tube?
auditory tube
68
Allows air to enter Middle Ear & provides pressure equalization with atmospheric pressure to maximize Tympanic Membrane mobility
eustachian tube
