Document Summary

Sensation: the conversion of energy from the environment into a pattern of response by the nervous system; the detection of stimuli. Iris: the colored structure on the surface of the eye surrounding the pupil. Light that passes through the eye passes through a layer of vitreous humor (jellylike substance) to strike the retina. Retina: a layer of visual receptors covering the back surface of the eyeball. Cornea: a rigid transparent structure on the outside of the eyeball. Lens: just below the cornea: can bend and vary in thickness to allow for accommodation of objects at different distances. Fovea: central area of the human retina; adapted for highly detailed vision. Located in the retina, in the back of the eyeball; very sensitive and very specialized. Only 5% of total receptors, but far more axonal connections to brain: send much more information. Rods: adapted for vision in dim light not color. Sound waves hit eardrum which cause it to vibrate.
