16
Q

what is the function of the sclera?

A
  • Gives shape to eyeball
  • Protects inner parts
17
Q

what is the function of the cornea?

A

covers the iris

principle refractive medium of eye

18
Q

what comrises the vascular tunic?

A
  • choroid
  • ciliary body
  • suspensary ligaments
  • iris
  • pupil
  • lens
19
Q

what is the function for choroid?

A

Nourishes retina

Pigment absorbs light rays so they do not bounce around in the eye

20
Q

what is the function of ciliary body?

A

Alters shape of lens (through ciliary muscle)

allows eyes to focus on an object

21
Q

what is the function of suspensary ligaments?

A

attach lens to ciliary body

22
Q

what is the function of the iris?

A

alters pupil size

23
Q

what is the function of pupil?

A

determines amount of light that passes

24
Q

what is the function of lens?

A

Focuses light rays on retina for image formation

25
Q

what comrpises the retina/ inner eye layer?

A
  • retina
  • ora serrata
  • optic nerve endings
  • optic disk
  • fovea
  • macula lutea
26
Q

what is the function of the retina?

A

role in image formation

27
Q

what is the function of macula lutea?

A

Point of highest image formation

28
Q

what is the function of optic disk?

A

blind spot

29
Q

what is the ora serrata?

A

scalloped edge that retina ends anteriorly at border with ciliary body

30
Q

what is the fovea?

A

depression in macula lutea

31
Q

what is the function optic nerve?

A

nerve that runs to brain to form image

32
