Dissection of head and neck from a posterior approach
Hypoglossal, accessory and vagus nerves; anterior rami of cervical nerves; internal carotid artery; internal jugular vein
The bodies of the first five cervical vertebrae have been sectioned in the midsagittal plane and the left halves removed. The cervical nerves have been retained approximately in their normal positions with the exception of the first nerve (16), which has been displaced superiorly. The anterior vertebral venous plexus (18) and longus colli and capitis muscles have been preserved.
