Controls the movement of the eye
White part of the eye, thick, tough, protects the eye. The transparent potion of it is known as the cornea
First internal layer of the eye, contains photoreceptors (rod and cone cells)
More common in the periphery of the retina
Used more in nighttime time vision
Used to see black/white
Concentrated in the fovea centralis
Used in daytime vision
Used to see color
Layer in between the Sclera and Retina
Absorbs all light that does not directly hit a rod or cone cell
Point in the retina (looks like a pinprick) in which cone cells are abundantly concentrated.
Modified end of the dendrites in the optic nerve concentrate here.
Axons of the cells in the fovia centralis meet here to form this nerve
Transmits information gathered by the eye to the brain.
Provide nutrients to the eyes various parts (excluding the cornea)
Spot in which the optic nerve begins, their are no rod or cone cells in this location.
Brain compensates by covering it with an image based on the data it is receiving
Gel like substance in the posterior chamber, gives structure to the eye and maintains its shape.
Cilary Muscle Bodies
Controls the shape of the lens
Makes the aqueous humor
Provides nutrients to the aqueous humor
Strength will deteriorate with age
Colored layer of the Eye
Controls the amount of light let into the eye (size of the pupil)
External layer of the eye
Protects the eye from bacteria
Basically a hole in the eye
Allows for light to enter the eye
Size is controlled by the Iris
Focuses light to the fovea centralis
Transparent liquid behind the cornea
Delivered nutrients to the cornea
Transparent part of sclera (so you can see)
Begins the light focusing process
No blood vessels
Receives nutrients from the aqueous humor
Chamber behind the cornea
Filled with aqueous humor
Help control the shape of the lens to focus light
