Match the structures of the eye with their appropriate statement. Light enters the eye here Control the shape of the lens Focuses the light onto the back of the eye Gives your eyes their color the "white" of the eye Watery fluid filling the anterior segment of the eye Viscous liquid filling the posterior portion of the eye Area of highest concentration of cones, and thus highest visual acuity Part of the retina that lacks photoreceptors Makes up the majority of the vascular layer Contains the rod and cone photoreceptors Forms the aqueous humor 1. Aqueous humor 2. Choroid 3. Ciliary muscles of ciliary body 4. Ciliary processes of ciliary body 5. Cornea 6. Fovea centralis 7. Iris 8. Lens 9. Optic disc 10. Retina 11. Sclera 12. Vitreous humor

Activity 3: Eye Structures Identify the eye structures listed in the left column on the models. Write a description in the middle column and indicate the wall layer that contains each structure in the right column. Use the abbreviation F for fibrous layer, V for vascular layer, and R for retinal layer. Eye Structure Sclera Cornea Choroid Ciliary body Iris Pupil Ora serrata Optic disc Macula lutea Lens Optic nerve Activity 4: Fluid-Filled Spaces of the Eye Use the eye model to identify the spaces of the eye that are listed in the left column and write a description in the middle column. Write the fluid humor that occupies each space in the right column. Space Anterior segment Anterior chamber Posterior chamber Posterior segment

Match the function or definition to the structure: _____ A. Lens 1. Has pigment producing cells and blood vessels, keeps inside eye dark _____ B. sclera 2. The colored part of the eye, which controls amount of light entering _____ C. retina 3. Area where the nerve fibers from retina converge and leave eye _____ D. fovea centralis 4. Region of the retina that provides the sharpest vision _____ E. iris 5. Transparent structure found in eye and held in place by ligaments _____ F. optic disc 6. White portion of the eye is the outer layer _____ G. choroid coat 7. Inner layer of the eye which contains the photoreceptors
