Which of these parts holds the lens in place?1 aqueous humor iris canals of Schlemm cornea zonules of Zinn Which of these leads right into the optic nerve?1 bipolar cell amacrine cell horizontal cell ganglion cell You blind spot is right over your fovea.1 True False When it is dark, the rods are switched on and are releasing neurotransmitters.1 True False Which is larger, the macula or the fovea?1 fovea macula Which is smaller, rhodopsin or retinal?1 retinal rhodopsin Which one of these allows us to see at night?1 rods cones The retina sees images upside down.1 True False Which cell part makes a microtubule highway through a narrow passage in the rod and cone cells?1 mitochondria ribosomes nucleus centrioles Golgi bodies Which of these parts bends light?1 cornea iris retina optic nerve ciliary body You have more rods than cones.1 True False What happens when a photon of light hits the retinal molecule?1 It changes shape and becomes straight. It starts an action potential. It falls out of the rhodopsin molecule. It loses an electron. It regenerates. Where will you find the highest number of cone cells?1 They are evenly spaced all over the retina. At the outer edges of the retina In the macula Which of these let the rods and cones communicate with each other?1 amacrine cells ganglion cells bipolar cells horizontal cells What holds the rhodopsin molecule in place?1 cytoskeleton microtubules Golgi bodies phospholipid membrane retinal molecules To view things farther away, the lens must become flatter.1 True False Pigmented epithelial cells regenerate when damaged, just like skin cells.1 True False Which of these is a color that cones don’t respond to?1 red yellow green blue Which amino acid to we find functioning as a neurotransmitter at the ends of rods and cones?1 glycine glutamate glutathione lysine Which of these is NOT a job that the pigmented epithelial cells do?1 Form a protective barrier so that germs stay out. Nourish the rod and cone cells. Absorbs extra photons of light. Prune the tips off the rod and cone cells and recycle them. Provide a connection between rods and cones so they can cooperate. 62: The eye (anatomy) 64: The Brain (part 1) Back to: 63: The eye (physiology)
