The document provides instructions for dissecting an eyeball to identify its internal parts. It describes making cuts around the iris to remove the cornea and iris, then pouring out the humor to expose the choroid and retina. It lists the major external and internal parts of the eye, including the sclera, optic nerve, cornea, iris, pupil, lens, choroid, retina, and humor. A picture is referenced to show the location of these parts.

5. Carefully pour out humor.
6. Carefully remove choroid and expose retina.

3. (2) Finding Parts
• Sclera = White part of eye

• Cornea = Outer covering on center of eye
• Iris = Colored ring
• Pupil = Hole in center of iris
• Lens = Hard, cough-drop-like structure
• Choroid = Dark, metallic tissue
• Retina = Flesh colored tissue
• Humor = Clear goo
