Dissection of anterior aspect of vertebral column
Cervical region.
The longus capitis muscle has been divided close to its origins (15) from the transverse processes of the third to the sixth cervical vertebrae and also at its insertion (1) into the occipital bone. The removal of the belly of this muscle has exposed the longus colli muscle (13) and the anterior arch of the atlas (9).

- Nasal cavity
- Nasopharynx
- Oropharynx

- Upper pointer: Internal carotid artery (within carotid canal, accompanied by internal carotid plexus) Lower pointer: Jugular foramen (opened)
- Lateral rectus capitis muscle
- Upper pointer: Hypoglossal nerve (XII) Lower pointer: Anterior rectus capitis muscle
- Upper pointer: Anterior atlantooccipital membrane Lower pointer: Anterior arch of atlas (covered by connective tissue)
- Transverse process of atlas
- Lateral atlantoaxial joint (pointer on joint capsule)
