A section through the external nostrils, premaxillary palate, larynx and C-3 spinal ganglion.

Observe:
1. Epithelial plugs in the external nostrils.
2. The well-developed tongue muscles and the hypoglossal nerve.
3. The submandibular duct, gland and ganglion.
4. The arytenoid and thyroid cartilages of the larynx and the greater horn and body of the hyoid apparatus.
5. The dorsal and ventral primary rami of a spinal nerve.
