Physiology of the Sheep Eye

• LENS- transparent, works with the cornea to helps refract light to be focused on the retina.

• BLIND SPOT- a place in your vision where you cannot see some objects 

• RETINA- the light-sensitive tissue lining the back of our eye. Light rays are focused onto the retina through our cornea, pupil and lens. 

• PUPIL-a hole located in the centre of the iris of the eye that allows light to strike the retina

• IRIS- thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina.

• SCLERA- the white outer layer of the eyeball. At the front of thnuous with the cornea at the front of the eye

• OPTIC NERVE- each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye.

• AQUEOUS HUMOR-transparent, watery fluid that comes out when you cut the eye 

• CHOROID- the pigmented vascular layer of the eyeball between the retina and the sclera.

• VITREOUS HUMOR- is the clear gel that fills the space between the lens and the retina of the eyeball 

• CORNEA- the transparent layer forming the fro

• CILIARY BODY-  is a part of the eye that includes the ciliary muscle, which controls the shape of the lens- 

• EYE LID- each of the upper and lower folds of skin that cover the eye when closed. protects the eye from getting damaged/scratched by any little particles such as dust

• TAPETUM LUCIDUM- what allows animals to see in the dark.
