A section through the dorsal edge of the tongue and the C-2 spinal ganglion.

Observe:
1. The vomeronasal organ on the medial wall and the inferior concha on the lateral wall of the nasal cavity.
2. The relative positions of the nasal cavity, oral cavity, oropharynx and laryngeal pharynx.
3. The palatine fossa (pouch 2) in the lateral wall of the oropharynx.
4. An enamel organ and the maxilla in the roof of the oral cavity.
5. The atlanto-axial joint.
