Cranial Nerve Functions Quizlet is the easiest way to study, practice and master what you’re learning. These impulses travel from one neuron to another by crossing a synapse. The posterior, or dorsal, roots of spinal nerves carry sensory information from the areas they serve back to the brain. Due to its widespread functions, vagus nerve pathology is involved in a vast variety of clinical cases. The olfactory nerve is the shortest nerve in the body and it does not enter the brain stem. The most significant systemic nerve to come from this plexus is the sciatic nerve, which is a combination of the tibial nerve and the fibular nerve.
