Question

why accessory nerve is not spinal nerve even it emerges from spinal cord?

Answer 1

Accessory Nerve. The accessory nerve (eleventh cranial nerve)emerges from the skull through the jugular foramen in a shared sheath with the vagus nerve. It has two roots, a cranial root from the medulla and aspinal root from the lateral portions of the ventral column.

Answer 2

The spinal accessory nerve is notable for being the only cranial nerve to both enter and exit the skull. This is due to it being unique among the cranial nerves in having neurons in the spinal cord. After leaving the skull, the cranial component detaches from the spinal component.
