Opening that allows light in

3

Iris

Increase/decrease pupil size to control light levels

4

Protective outer coat,
Muscles attach to it

5

Upper/Lower Eyelids

Protect eye and decrease visual stimuli when sleeping

6

Lens

Change focal distance of the eye to allow to be able to focus on objects at various distances

Liquid that fills the eyeball,
Maintain shape of the eyeball

10

Choroid

Houses arteries and blood vessels that nourish the back of the eye

11

Retina

Receives light focused from the lens,
Convert light to neural signals,
Send signals to brain

12

Macula Lutea

Responsible for sharp, detail central vision,
High concentration of cones

13

Fovea Centralis

Highest concentration of cones in the macula lutea,
Most focused part of retina

14

Optic Disc

Point of exit for ganglion cell axons (optic nerve) leaving the eye,
Creates blind spot because no rods or cones

15

Optic Nerve

Transfer visual information from retina to the brain

16

Lacrimal Gland

Produces tears

17

Nasolacrimal Duct

Carries tears from lacrimal sac to nasal cavity
