Textbook Question
Chapter 13, Problem 12CYU

For each of the following, indicate whether it applies to rods or cones: vision in bright light; only one type of visual pigment; most abundant in the periphery of the retina; many feed into one ganglion cell; color vision; higher sensitivity; higher acuity.
Provide a step by step list of visual sensation through visual processing. Begin at light entering the
eye through signal transduction, to the circuitry involved in the brain in understanding the "what"
and "where" of the object. Be sure to review the specific criteria outlined in the rubric.

Match the labelled eye structure with the correct eye condition or eye function.
Contains the photoreceptors (rods and cones)
Glaucoma results if this fluid is not drained properly
Sensory neurons to the brain
: Captures stray light and contains nourishing blood vessels
Contains a high concentration of cones
Cataracts can develop in this structure
Refracts (bends) light rays into the eye
The blind spot: no photoreceptors are located here
Protects and supports the eyeball
Supports the eyeball with the gel-like fluid
The opening for light to enter the inner eye
