Anatomy of Ear: Tympanic Membrane

The tympanic membrane is placed in the canal at an angle of _____ degrees with the floor.

a). 30

b). 45

c). 55

d).135

e).150

correct answer: c

Tympanic membrane is a thin semi-transparent membrane which separates middle ear from the external ear.

It is oval in shape and measures approximately 10 mm vertical plane and and 9 mm in horizontal plane. It is obliquely placed at the end of the ear canal at an angle of about 55° with the floor of the meatus.
