EYE STRUCTURE
DESCRIPTION / FUNCTION
1
move eyeball
tunics: fibrous, vascular, nervous
3
outer layer, composed of sclera and cornea
4
"white" of eye, tough due to amount of collagen fibers, gives eye it's
shape and protects inner anatomical parts
transparent epithelium that protects front of eye and helps focus
light onto the retina
uvea, middle layer composed of choroid, ciliary body, and iris
7
inner retinal layer
8.
major vascular portion that lines internal surface of sclera
9.
changes shape of lens to adapt to near and far vision
10
coloured portion consisting of circular and radial smooth muscle
11
exact center of retina
12
small depression in center of macula lutea that contains only a high
concentration of cones, sharp central vision for detailed vision
13
only place where arterial blood vessels can be viewed without
opening body
14
where optic nerve and retinal vessels enter and exit eyeball, area
where there are no cones or rods, bilateral vision and saccade correct
for this
15
rods & cones
16
avascular, transparent refractory structure posterior to pupil and iris,
capsule with crystalline proteins arranged in layers
17
attaches lens to ciliary muscle of ciliary body, fine tune focusing of
light on the retina
18
anterior to lens
19
part of anterior cavity anterior to the iris, filled with aqueous humor
20
part of anterior cavity posterior to the iris, filled with aqueous humor
21
lies between the lens and the retina
22
transparent jellylike substance that holds the retina flush against the
choroid (even surface), helps maintain intraocular pressure, formed
during embryological development and is not replaced, shrinkage can
lead to retinal detachment
23
radial muscle and circular muscle in center
