vitreous chamber,"large inner cavity of the eyeball filled with vitreous humor (jellylike substance)"
outgrowth of brain
retina,"light sensitive element, cannot be replaced or repaired, back of the the elaborate network of photoreceptors and interneurons at the back of the eye that is responsible for sensing light"
eye, the most complex part
photoreceptorsÂ ,"specialized sensory cells in the retina that respond to light"
bipolar cells,"cell in the inner nuclear layer of the retina that forms part of the straight pathway between the photoreceptors and ganglion cells"
ganglion cells,"send information to the brain"
