(33 cards)
3 layers of the eye
- Fibrous layer
- Vascular layer
- Inner layer
what does the fibrous layer consist of
- Sclera
2. Cornea
what does the vascular layer consist of (3)
- Choroid
- Ciliary body
- Iris
what does the inner layer consist of (1)
retnia
Sclera is what portion of the eye
the white part
Aids in light refraction, with minimum distortion (what eye structure)
cornea
what is the innervation to
V1 (ophthalmic)
layer between the sclera and the retnia
choroid (this is the blood supply)
3 sections of the Ciliary body
- Ciliary process
- Ciliary muscle
- zonular fibers
Ciliary process function
aqueous humor
Ciliary Muscle function
reshapes lens
Zonular Fibers function
connects ciliary muscle to lens
effect on the ciliary muscle contraction on the else
lens becomes spherical
accomodation helps you see object that are (close far)
close
what changes the size of the pupil
iris
what is the name of the 2 muscles that change the size of the iris and thus the pupil
Sphincter pupillae: Parasympathetic
via CN III
Dilator pupillae: sympathetic
Horners syndrome what happens to the pupil
constricted
Is the retina innervated
no
where in the eye are the photo receptors
retnia
what part of the eye does High acuity vision
Macula and Fovea
Entry of optic nerve,
blind spot
optic disc
Sphincter pupillae sympathetic or parasympathetic
parasympathetic V3
Partial or complete opacity
of the lens
Cataracts
Chambers of the eye
