Term
what separates the middle from the external ear?
Definition
tympanic membrane
Term
connects the middle ear to the nasopharynx?
Definition
Eustachian tube- makes the pressure in the middle ear the same as atmospheric
Term
what are the two muscles of the middle ear? and what nerve innervates them?
Definition
tensor tympani- inserts on tympanic membrane. Innervated by V.
stapedius- inserts on stapes- innervated by VII

what is brought about by contraction of the tensor tympani?
Definition
dampens the oscillations of the tympanic membrane
Term
what does the stapedius do when it contracts?
Definition
stapedius changes the action of the stapes from a piston action to a rocking motion- this is to dampen the AMPLITUDE OF SOUND while the frequency is maintained.
