Summary Introduction
To Determine:
Whether the given statement is true or false.
Introduction:
The nervous system can be defined as a highly complex portion of an animal which directs its actions and sensory messages by transmitting signals to and from diverse body parts. The basic unit of the nervous system is known as the nerve cell or neuron.

After reading Chapter 11, “The Nervous System: The Brain, Cranial Nerves, Autonomic Nervous System, and the Special Senses,” of the Fundamentals of anatomy and physiology textbook, answer the following questions:
List all cranial nerves and their function.
Using your own words, describe how cranial nerves are related to the special senses.
Testing for neurological function involves a series oftests of functions associated with the cranial nerves. Whatfunctions, and therefore which nerves, are being tested byasking a patient to follow the tip of a pen with their eyes?
