accessory XI nerve nucleus

accessory neural nucleus

The spinal accessory nucleus lies within the cervical spinal cord (C1-C5) in the ventral horn. The nucleus ambiguus is classically said to provide the 'cranial component' of the accessory nerve. However, the very existence of this cranial component has been recently questioned and seen as contributing exclusively to the vagus nerve. The terminology continues to be used in describing both human anatomy, and that of other animals.
