(a) Trace the pathway light would take through the eye listing order the structures and spaces it would pass through starting from outside the eye to the specific part of the brain where these signals are interpreted. Note their function as well

(b) Trace the pathway tears would take listing in order the structures and spaces they would pass over/through starting with the lacrimal gland and ending in the stomach.

(c) Trace the pathway sound waves would take through the ear listing in order the structures and spaces it would pass through starting from the auricle and ending at the round window & part of the brain where signals are interpreted. Hint don't forget about the nerves, tracts, and brain structures involved.

(d) List the three divisions of the ear,
