Document Summary
Sensation: detection, sensory receptors, transmission to brain (hearing a song) Iris: thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Cornea: the transparent part of the eye that covers the front portion of the eye, the main function is to refract, or bend, light. Lens: changes the focal distance of the eye, and focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned at various distances. Specific: fovea, retina, optic nerve, retinal blood vessels. Retina: the nerve layer that lines the back of the eye, senses light, and creates impulses that travel through the optic nerve to the brain. Macula: small area in the retina that contains special light-sensitive cells. Fovea: a tiny pit located in the macula of the retina that provides the clearest vision of all.
