There are 12 pairs of nerves that originate from the lower surface of the brain and pass through openings in the skull, one of each pair on each side. These are the cranial nerves that control facial and throat motions including swallowing, speech, tear production, smell taste and vision. The cranial nerves are the only nerves that do not originate from the spine.
Injury to any of these cranial nerves can occur from a number of causes such as head trauma, fetal positioning or forceps pressure or a variety of surgical procedures. The different cranial nerves, when injured, produce different symptoms, many of which can be lifelong, effecting mental, physical, financial and social capacities.
