Scientific notes
Libelle of note
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).
