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 |
