Basic Eye Functions, Locations
| Answer | |
|---|---|
| Photorecptors | Located in Retina |
| Opsin | Protein |
| Canal of Schlemm | Drains Aqueous Humor Located in Anterior Cavity |
| 3 Layers of the Eye | Sclera Chorid Retina |
| Lacrimal Gland | Manufactures Tears |
| Refraction | Bending of Light Rays to Focus on the Retina |
| Function and Location of Sclera | Outermost layer Protects Gives Eye Characteristics "White of Eye" |
| Function and Location of Choroid | Provides all Nutrients to Eye Middle Layer |
| Lens | Bends (refracts) Light to Focus in Eye |
| Anterior Chamber | Between Cornea and Iris |
| Anterior Cavity | Between Cornea and Lens Contains Aqueous Humor |
| Function and Location of Retina | Inner Layer Responsible for Vision Made of Rods and Cones Rods and Cones turn into Electric Impulses |
| Conjuctiva | Thin Membrane (film) Covers Eye Protects Eye |
| Pupil | Opening in the Center of the Iris Bright Light Constricts (closes) Dim Light Dilates (open) |
| Macula (Lutea) | High Concentration of Cones Area of Sharpest Vision No Rods |
| Vitereous Humor | 3 Functions Solid Gives eye Characteristic Shapes (Hard or Soft) Responsible for Refraction |
| Lecrim | Tears |
| Function and Location of Cornea | 1st Structure Light Travels to Tough Transparent Outer Layer |
| Function and Location of Optic Nerve | Connects Eye with Brain Located in the Back of the Eye |
| Retinal | Pigment with Vitamin A |
| Posterior Chamber | Between Iris and Lens |
| Aqueous Humor | Thin Watery Fluid that fills the Space Between the Cornea and Iris Not Tears Anterior Chamber |
| Pathway of Light Traveling into the Eye | Cornea Pupil Lens Retina Optic Nerve |
| Posterior Cavity | Lens to Optic Nerve Contains Viterous Humor Behind Lens |
| Occipital Lobe | Area of Brain which Vision Occurs |
| Rhodopsin | Main Ingredient of Rods and Cones When Light Hits this Causes a Split called Retinal and Opsin |
| Iris | Controls Light Inside the Eye |
