n 5) What are the special senses and which cranial nerve(s) controls each one? (10-points) 6) Using the attached "Diagram B" illustrate the neuronal pathway that causes pupillary dilation. Using the attached "Diagram C" illustrate the neuronal pathway that causes pupillary constriction. Then in a short paragraph explain your illustration making sure to include where the cell bodies for the preganglionic and postganglionic neurons are located, the structure of the axons, where the neurons synapse (name of autonomic ganglion), the neurotransmitters used and the effector. (20-points)

Explanation / Answer

The special senses are those that have special organs devoted to their function.These are the highly complex receptor organs only for a particular sense. They have specialized sensory receptors or nerve endings unlike 'touch', which is a general sense that has nerve receptors all over the body.The special senses, the organs involved and the cranial nerves specialized for each are tabulated below:

Special senses Organ Cranial Nerve Vision eye Optic nerves Hearing and balance ear Vestibulocochlear Taste tongue Facial Smell nose Olfactory
