Document Summary
Function: contains blood vessels that supply eye tissue with nutrients & oxygen contains melanin, which absorbs light reflected from the retina. Function: contains photoreceptors that respond to light by generating electrical signals. 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. List the tunics of the eye and the structures that can be found in each. Provides some degree of protection; attachment site for extra-ocular muscles. Consists of blood vessels, lymphatics, and intrinsic eye muscles. Regulates the amount of light entering the eye. Secretes and reabsorbs jelly-like fluid (aqueous humor) Function: contains blood vessels that tissue with nutrients & supply eye oxygen contains melanin, which absorbs light reflected from the retina.
