The vagus nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches. It is also part of a group together with the glossopharyngeal and accessory nerves that passes through the '''jugular foramen''' which is termed the '''vagus group'''. The vagus nerve innervates structures related to the fourth branchial arch. The vagus nerve has cell bodies that are referred to as '''nucleus ambiguus'''. | The vagus nerve is part of the group of cranial nerves responsible for innervation of structures derived from the branchial arches.
