1.
Briefly review the anatomy of the cochlea. What is the cochlear blood supply?
2.
Discuss the effects of the pinna, head and ear canal on the transmission of sound.
3.
What is impedance mismatching? How does the middle ear compensate/correct this problem?
4.
Describe the role of the middle ear muscles in sound conduction. (for extra points….what is the innervation for each?)
5.
Discuss the effects of TM perforation and middle ear effusions on sound conduction?

6.
Discuss the inner ear fluids.
7.
Give us an in-depth review on the function of the inner and outer hair cells.
8.
Review the basilar membrane and traveling wave.
9.
Describe the final pathway of neural stimulation from the cochlea to the brain.
10.
What is gain? Does the shape of the ear canal influence gain?
