Chapter 12, Problem 6CR
Summary Introduction
To review:
The function of three bones (malleus, incus, and stapes) of the middle ear.
Introduction:
The ear is divided into three regions outer, middle, and inner. The middle ear is an air-filled chamber residing in the skull’s temporal bone. It is bridged by three small bones namely, malleus or hammer, incus or anvil, and stapes or stirrup.

Describe the overall function of the three bones (the malleus, the incus, and the stapes) of the middle ear.
(a) choose one part of the auditory conductive mechanism--the outer ear or middle ear--and describe how sound is transduced (changed from acoustic energy to mechanical energy) through that part of the auditory system, and
(b) comment on how the anatomy of that part of the ear enables normal auditory conductive physiology.
(a) What is the difference, if any, between a semicircular canal and semicircular duct? Between the cochlea and cochlear duct? (b) Name the three parts of the membranous labyrinth of the internal ear. Which of these parts is for hearing, and which are for balance?
