Document Summary
List the structures of the eye, their function and location. Contains aqueous humor made by ciliary bodies (replaced ever 90 mins) location: between the cornea & lens. Contains aqueous humor made by ciliary bodies (never replaced) location: between the cornea & lens. Contains vitreous humor; never replaced jelly-like fluid. Function: contains blood vessels that supply eye tissue with nutrients & oxygen contains melanin, which absorbs light reflected from the retina. Function: ring of muscle tissue that encircles the lens holds lens in place and changes its shape: location: muscle behind cornea. Function: contains photoreceptors that respond to light by generating electrical signals: types of photoreceptors: Region of the retina with greatest concentration of cones. Function: objects are focused here for sharp vision. Location: small rounded pit in middle of the retina. Function: cranial nerve that carries light stimuli to the brain for interpretation/storage. Contains aqueous humor; water fluid that is continuously replaced.
