The area bound in front by the cornea and in back by the lens and filled with aqueous |
|
|
Aqueous |
A clear, watery solution in the anterior and posterior chambers |
|
|
Artery |
The vessel supplying blood to the eye |
|
|
Canal of Schlemm |
The passageway for aqueous fluid to leave the eye |

Choroid |
carries blood vessels and is the inner coat between the sclera and the retina |
|
|
Ciliary Body |
unseen part of the iris, together with the ora serrata from the uveal tract |
|
|
Conjunctiva |
a clear membrane covering the white of the eye (sclera) |
|
|
Cornea |

|
Iris |
provides eye color and functions like the aperture on a camera, enlarging in dim light and contracting in bright light. The aperture itself is called the pupil |
|
|
Lens |
helps to focus light on the retina |
|
|
Macula |
a small area in the retina that provides our most central, acute vision |
|
|
Optic Nerve |
conducts visual impulses to the brain from the cornea |
|
|
Ora Serrata & Ciliary body |
form the uveal tract, an unseen part of the iris |
|
|
Posterior Chamber |
located behind the iris, in front of the lens, filled with aqueous |
|
|
Pupil |
the opening, or aperture, of the iris |
|
|
Rectus Medialis |
One of the six extra ocular muscles of the eye |
|
|
Retina |
The innermost coat of the back of the eye, formed of light sensitive endings that carry the visual impulse to the optic nerve. The retina may be compared to the film of a camera |

|
Sclera |
the white of the eye |
|
|
Vein |
A vessel that carries blood away from the eye |
|
|
Vitreous |
a transparent, colorless mass of soft, gelatinous material filling the eyeball behind the lens |

Primary function to elevate and retract upper eyelid |
|
|
Orbicularis Oculi Muscle |
Close the eyelids |
|
|
Cones are |
Color sensitive, fine detailed vision and located towards posterior of retina. 6 million |
|
|
Rods are |
Light sensitive and for low vision. 120 million, located nearby front of retina |
