Eye Dissection Analysis

In the eye dissection, we dissected a sheep eye and walked through the different parts of the eye and learned about what each part did. Below are some pictures of the eye from our lab:

Here is a diagram of the eye, which is much easier to follow: 

Let's go through the anatomy of the eye. All the major parts of the eye are labeled in the diagram:
Structure A is vitreous humor, structure B is the lens, structure C is cornea, structure D is pupil, structure E is iris, structure F is retina, structure H is the choroid, and structure G is the optic nerve. My favorite part is the choroid because I really like the shimmery blue/green color of it. It also looks so cool when light shines through it because there is almost a fingerprint like "watermark" that shows up.

For the physiology of the eye, there are several major components. For example, there are many muscles around the eye that allow for eye movement, and fat that acts as cushion around the eye. The cornea protects the eye and allows light to pass through. large region of vitreous humor is the fluid between the cornea and the lens, and its function is to support eye shape. The lens focus images on the retina, and the retina is filled with rods and cones to take in different images of light that are then funneled to the back of the eye to the optical disk/blind spot. Finally, at the very back of the eye is the optic nerve cross (optic chiasm) that crosses over to the respective left and right hemispheres of the brain. The left eye's optic nerve crosses over to the right brain hemisphere, and the right eye's optic nerve crosses over to the left brain hemisphere.
