A note on the anastomoses between the hypoglossal nerve and the cervical plexus.
A series of 80 dissections was performed to define the anastomoses between the cervical plexus and the hypoglossal nerve (XII), the superior anastomosis between the trunk of XII and the ansa of the atlas from the cervical plexus; the ansa cervicalis, traditionally known as the ansa of the XIIth cranial nerve or hypoglossal ansa, formed by the direct junctional anastomosis of the descending branch of XII and the internal descending branch of the cervical plexus. The origins, form, branches and chief relations are defined in in the present study.
