A section through the C-6 spinal ganglion and the primitive palate.

Observe:
1. The vomeronasal nerve coursing from the vomeronasal organ.
2. The relation of the maxillary process and nasal elevations to the primitive palate.
3. The rostral (fourth pouch) and caudal (third pouch) parathyroid buds dorsolateral to the thyroid gland.
4. The trachea ventral to the esophagus.
5. The edge of the shoulder.
