Abstract:

Through the jugular foramen.The intracranial dorsal vagal ramus arises from the vagal root and enters its own ganglion. It anastomoses with the posterior lateral line nerve.The vagus nerve divides into three branchial trunks and a truncus visceralis.Each branchial vagal trunk has an epibranchial ganglion. Distal to the ganglion each trunk branches into rami pharyngeus, anterior and posterior pretrematic and a posttrematic. The first branchial vagal trunk anastomoses with the vagal sympathetic ganglion.The nervus vagus carries general somatic sensory fibres to the skin, general viscerosensory fibres to the pharyngeal epithelium, special viscerosensory fibres to the gill rackers and the taste buds and visceromotor fibres to the levators and the adductor arcuales branchiales and the obliquus ventrales muscles of the second, third and fourth holobranchs and transversus dorsalis and ventralis muscles.In addition it also carries vegetative fibres (parasympathetic) for the blood vessels and the muscles of the gill filaments.
