Question 16

What are the three bones of auditory ossicles

Answer 16

Malleus, incus, and stapes

Question 17

What do the bones of the auditory ossicles do

Answer 17

Bridge the tympanic membrane and inner ear, transferring vibrations between the parts. Form a lever system that helps increase the force of vibrations as they pass from tympanic membrane to oval window. Transfer vibrations from larger surfaces of tympanic membrane to smaller areas of oval window, so the vibrations strengthen as it travels from outer to inner ear.

Question 18

True of false: the pressure the staples of the ear applies at the oval window is about 22 times greater than that which sound waves exert on the tympanic membrane

Answer 18

True

Question 19

Answer 20

Divides the bony labyrinth of the cochlea into upper and lower compartments.

Question 21

What is the upper compartment of the cochlea shelf, what does it do

Answer 21

Scala vestibule; leads from the oval window to the Apex of the spiral

Question 22

What is the lower compartment of the cochlea shelf; what does it do

Answer 22

Scala tympani; extends from the apex of the cochlea to a membrane covered opening in the wall of the inner ear called the round window

Question 23

The compartments of the cochlea are filled with what

Answer 23

Perilymph

Question 24

What is the small opening of the cochlea that connects fluids in the chambers

Answer 24

Apex

Question 25

What is a portion of the membraneous labyrinth that lies between the 2 bony compartments and is filled with endolymph

Answer 25

Cochlear duct

Question 26
