- Cornea- the transparent layer in front of the eye that protects it (was very hard and almost like a plastic during the dissection)
- Sclera- the white outer layer of the eyeball and serves to protect the eye/contain its components (based off of observation) and connects the muscle
- Optic nerve- each pair of cranial nerves connect at the back of the eye; transmit signals to the brain from the retina at the back of the eye
- Iris- a circular structure that controls the diameter of the pupil, thus the amount of light that enters the eye
- Pupil- hole at the center or the iris that allows a certain amount of light into the eye
- Ciliary body- controls the shape of the len, tissue that supplies eye with oxygen
- Choroid- the pigmented vascular layer of the eyeball between the retina and the sclera;
- Tapetum lucidum- lying right behind the retina, the tapetum lucidum is a refractory material that allows animals to see in the dark by reflecting the light (reason why animals eyes seem to flash back when photos are taken of them)
- Retina- essentially the film in the camera; very thin and was VERY easy to peal back in the dissection
- Lens- transparent, light bending structure, felt like a marble almost, like a marble split in half
- Vitreous humor- clear gel that fills the space between the lens and the retina; is the ‘cushion’/filler/place holder for the lens
I'm currently unaware of what my blog will be about. As time progresses I will update my description with what I will be posting.
