Dissection of anterior aspect of vertebral column
Cervical region.
The left half of the head has been previously dissected in connection with the anatomy of the head and neck .In this view, in which the tongue has been removed and the wall of the pharynx has been sectioned close to the midline, the cervical sympathetic trunk and the prevertebral muscles are visible in situ. The prevertebral layer of the cervical fascia has been removed to the left of the midline.
