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