Question
Chapter 13.2, Problem 1QC
Summary Introduction
To review:
The functions and the Roman numeral assigned to the following cranial nerves:
a. Olfactory nerve
b. Optic nerve
c. Vestibulocochlear nerve
Introduction:
The cranial nerves originate directly from the brain stem and are involved in transferring signals from and to the brain. The cranial nerves arise in pairs, and there are twelve pairs of cranial nerves in the human body. In total, there are 24 cranial nerves. To avoid confusion, each cranial nerve is assigned a Roman numeral, which represents the site of its attachment in the brain. The name of a cranial nerve suggests its function.
