| 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. |

| 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. |
