Create a scientifically accurate 3D medical educational animation about the anatomical overview of the human maxillofacial region.
Show a realistic human head and neck, then smoothly transition into a clean anatomical visualization of the maxillofacial region.
Clearly show:
* oral cavity
* upper and lower lips
* cheeks
* tongue
* hard palate and soft palate
* gingiva
* teeth
* maxilla
* mandible
* major salivary glands: parotid, submandibular and sublingual glands
* major blood vessels
* regional lymphatic vessels and lymph nodes
Use realistic human anatomy and accurate spatial relationships between all structures.
Use a professional medical-school educational animation style, realistic 3D anatomy, clean neutral background, soft medical lighting, slow smooth camera movement and clear close-up transitions.
The purpose of the animation is to introduce the anatomical structures that participate in the immune defense of the maxillofacial region.
Do NOT invent anatomical structures.
Do NOT show incorrect anatomy.
Do NOT mix blood vessels with lymphatic vessels.
Do NOT show fantasy or artistic anatomy.
Keep all anatomical proportions and locations scientifically accurate.
Add simple, clean English labels for the main structures only.
Duration: 8–10 seconds.
High anatomical accuracy.
Medical textbook-quality visualization.
