of the eardrum.

• Eustachian (auditory) tube

19
These 3 labyrinths provide us with a sense of
equilibrium.

• Semicircular canals

20
This structure functions in hearing and is
divided into the scala vestibule, scala media,
and scala tympani.

• Cochlea

21
This structure contains the hair cells which
enables us to hear.

• Organ of Corti

22
When stability is maintained while the head and
body are still, it is known as _________
equilibrium.

• Static

23
These bony chambers located between the
semicircular canals and the cochlea help maintain
static equilibrium.

• Vestibules

24
These calcium carbonate grains in a macula
respond to gravity when the head is tilted.

39
Having a cloudy lens means you may have a

• cataract

40
This condition is caused from excessive aqueous
humor, thus increasing fluid pressure in the eye.

• Glaucoma
