Complete the pathway with the appropriate structure. (2 points each) Light rays enter eye where they are refracted by the _________A___________, a transparent structure on the anterior surface of the eye. Light rays continue through a hole in the iris known as the _________B___________, which changes size depending on the amount of light in the environment. Once inside the eye, light is refracted by the ________C____________ which is able to flatten when viewing faraway objects. Finally the image is focused on the ________D____________(the neural layer of the eye) and light is detected by __________E__________(type of receptors). These receptors create action potentials which are transmitted along the optic nerves where some fibers cross over at the __________F__________, then continue on as __________G__________ synapsing in the thalamus and terminating in the occipital lobe of the cerebrum.
