Q

what does the nervous tunic contain?

A

photoreceptors

18
Q

what do the rods respond to?

A

light

19
Q

what type of vision do cones allow us to see?

A

20
Q

what is the name of the protein in the retina?

A

rhodopsin

21
Q

what is the macula ?

A

the small center of the retina

22
Q

what is the center of the macula called?

A

the fovea centralis

23
Q

where is the optic disc?

A

medial to the macula

24
Q

what is the blind spot of the retina called?

A

the optic disc

25
Q

what are the 3 chambers of the eye?

A

the anterior, posterior, and vitreous

26
Q

what is the fluid inside the anterior and posterior chamber?

A

aqueous humor

27
Q

what secretes the aqueous humor of the eye?

A

the ciliary body

28
Q

what is the fluid inside the vitreous chamber?

A

virteous humor

29
Q

what is a purpose of the vitreous humor?

A

to hold the lens and keep pressure

30
Q

how does light enter the eye?

A

light passes through the cornea, the pupil allows it through, it is ficused through the lens, it then interacts with the optic nerve
