The "goo" that fills the sclera |
|
|
Term
|
Definition
First place light hits and goes through. It is the most refractive part of the eye |
|
|
Term
|
Definition
After light goes through the pupil, hits this part of the eye. It is suspended, meaning it can be focused via the lens shape. |
|
|
Term
|
Definition
After a signal is generated in the retina, goes through the optic nerve, and runs into this, which describes how the nasal side information from both eyes goes to the contralateral side of the brain, while the temporal side hits the ipsilateral side of the brain. |

Thin layer of tissue that is a projection from the CNS |

Term
Blood vessels function in the eye |
|
Definition
Supply the retina with nutrients |
|
|
Term
|
Definition
A little dip in the retina. It is area of highest acuity in vision |
|
|
Term
|
Definition
Area of the eye where the optic nerve passes through, on the nasal side of the eye. Leaves a blind spot |
|
|
Term
|
Definition
Sensory neurons of the eye. Receive the original signal. Project to bipolar cells, which then project to amacrine and horizontal cells, which then project to ganglion cells. |

Location of rods and cones, ganglion cells in eye |
|
Definition
Rods and cones are located in the back of the eye, while ganglion cells are located in the front (STUPID ORGANIZATION!!) |
|
|
Term
Primary function of rods, density |
|
Definition
High density. Rods are primarily for light and dark/peripheral vision |
|
|
Term
Function of cones, density |
|
Definition
Lower density, except in the fovea, where highly concentrated. Provide high acuity and color vision. |
|
|
Term
comparison of rod and cone disc segments |
|
Definition
Rod segments are larger/fatter, absorb more light. Physically stacked upon each other. High concentration of rhodopsin in discs - about 40,000 molecules per disc. |

red, blue, green, depicted via cone cells, and light/dark, via rods. |
