30
What are the three parts of the bony labberith
Vestibule Cochlea Semicircular canals
31
This is the egg shaped part of the bony labyrinth that has two membraneous sacs, Saccule and Utricle
Vestibule
32
These line each canal compartment and house crista ampullaris
Semicirular canals
33
This is the sprial bony chamber and it extends from the vestibule
Cochlea
34
This is the oval window of the Cochlea
Scala vestibuli
35
This is where sound terminates in the cochlea
round window
36
This is an imbalance of hearing that blocked sound conduction to the fluids of the enternal ear
Conduction Deafness
37
This is damage to the neural structures at any point from the auditory cells
Sensorineural deafness
38

Maculea
39
