ANS: sensory (afferent)division
explanation:
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem).
The peripheral nervous system has 12 pairs of cranial nerves that control much of the motor and sensory functions of the head and neck.
The optic nerve is the second cranial nerve, responsible for transmitting the special sensory information for vision. It transmits visual information from the retina to the brain.
The optic nerve contains only afferent (sensory) fibers, and like all cranial nerves is paired.
The optic nerve is considered to be part of the central nervous system, as it is derived from diencephalon during embryonic development.
The information received from the external environment passes to the rods and cones on the retina, and then to bipolar cells, ganglion cells, and ultimately to the optic nerve.

Questions 1 pts Humans and many other diurnal animals have three types of cones - one stimulated maximally by blue light, a second maximally stimulated by green light, and a third stimulated maximally by red light. How can human beings see colors such as orange, yellow and purple? When red cones are stimulated, they inhibit blue and green cones. When blue cones are stimulated, they inhibit only green cones. Green cones when stimulated, do not inhibit other cones, but do...
