The bodies of the first five cervical vertebrae have been sectioned in the median plane and their 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 internal vertebral venous plexus (18) and the longus colli and longus capitis muscles has been preserved.
