Taxonomic definition
Taxonomic definition An accessory nerve is a neural tree organ [organum arbor nervosum ] which has somas in the spinal chord and has a short path in the cranium entering the foramen magnum and exiting through the jugular foramen.
Notes
Although it was suggested that Cranial roots and Vagal communicating branches of the Nervus accessorius are uncommon (Lachman N, Acland RD, Rosse C 2002 Anatomical evidence for the absence of a morphologically distinct cranial root of the accessory nerve in man. Clin Anat 15:4-10; Ryan S, Blyth P, Duggan N, Wild M, Al-Ali S 2007 Is the cranial accessory nerve really a portion of the accessory nerve? Anat Sci Int 82:1-7), a recent microsurgical approach on 43 adult cadavers revealed that Cranial roots of the Accessory nerve exist in the majority of adult humans (Tubbs RS, Benninger B, Loukas M, Cohen Gadol AA 2014 Cranial roots of the accessory nerve exist in the majority of adult humans. Clin Anat 27:102-107).
