The skin and subcutaneous connective tissue have been removed.

1. Filament of inferior palpebral branch of infraorbital nerve
2. Angular head of levator labii superioris muscle
3. Alar branch of angular artery
4. Orbital part orbicularis oculi muscle
5. Infraorbital head of levator labii superioris muscle
6. Zygomatic head of levator labii superioris muscle
7. Angular artery
8. Communication between facial and infraorbital nerves
9. Depressor anguli oris muscle
10. Cutaneous nerve filaments from infraorbital plexus
11. Superior labial branch of infraorbital nerve
12. Labial glands
13. Orbicularis oris muscle (superior part)
14. Superior labial artery
15. Upper lip
16. Lower lip
17. Orbicularis oris muscle (inferior part)
18. Risorius muscle
19. Zygomatic branches of facial nerve (several cutaneous filaments appear to be branches of the facial nerve although these are presumed to contain sensory fibers which reach the central nervous system through the trigeminal nerve)
20. Accessory parotid gland
21. Parotid-rnasseteric fascia

23. Buccal branch facial nerve (VII)
24. Parotid duct (enclosed by sheath of connective tissue and plexus of veins)
25. Zygomaticus muscle
26. Anterior facial vein (incompletely filled with latex)
27. External maxillary artery
28. Filament of cutaneous colli nerve
29. Buccinator muscle
