Dissection of anterior and lateral regions of neck
Vertebral artery; gray communicating rami of cervical sympathetic trunk, left anterolateral view
The longus colli, rectus capitis anterior, rectus capitis lateralis and some of the intertransverse muscles have been cut away. In addition, the transverse processes of the atlas, epistropheus and fifth cervical vertebra have been cut so that the course of the vertebral artery (17) is visible. The artery did not pass through the transverse process of the sixth cervical vertebra in this specimen.
