A section through the C-5 spinal ganglion and primitive choana.

Observe:
1. The olfactory nerve coursing from the olfactory epithelium.
2. The primitive choana between the lateral palatine process and the nasal septum.
3. The origin of the nasolacrimal duct between the lateral nasal elevation and maxillary process.
4. The tongue tip in the primitive oral cavity near the primitive rima oris.
5. The caudal parathyroid bud derived from the third pouch of younger embryos.
