Basic Ear Anatomy

Sketch a picture of an ear and label the following:
Inner ear
middle ear
outer ear
pinna
tympanic membrane
cochlea
stapes
malleus
incus
What is the function of the following:
Pinna – direct sound waves into the auditory canal
tympanic membrane – reproduces the vibrations of the sound wave source.
ossicles – transmits vibrations between the tympanic membrane and the inner ear.
cochlea – fluid filled sack that helps hairs turn vibrations into nerve impulses.
semicircular canals – provide a sence of equilibrium.
What three bones make up the ossicles? Malleus, incus, and stapes.
What is the function of hairs in the ear? The hairs stimulate nerve impulses to be sent to the brain by way of the auditory nerve
