Study Notes
Floor of the Mouth (FOM)
- Horseshoe shape, thin, sensitive, and easily traumatized, due to its thin epithelium.
- Posterior part is not movable, creating the area of the tongue.
- Clinical Appearance:
- Reddish-pink appearance due to thin epithelium.
- Vascular blue in areas of veins.
- Shiny and moist due to salivary glands.
- Compressible and bouncy due to loosely attached underlying muscles allowing tongue movement.
Palate
-
Hard Palate:
- Firm, immobile, pink color, keratinized epithelium with no submucosa.
- Thicker medially and softer laterally.
- Innervated by the greater palatine and nasopalatine nerves.
- Blood supply: greater palatine artery.
-
Soft Palate:
- Moist, elastic, reddish-pink, non-keratinized stratified squamous epithelium with a thick submucosa.
- Innervated by the lesser palatine nerve.
- Blood supply: lesser palatine arteries.
Muscles of the FOM
- Mylohyoid: Origin: inner surface of mandible, Insertion: midline raphe, Action: elevates floor of mouth, Nerve Supply: Mylohyoid nerve, Blood Supply: Inferior alveolar, sublingual, and submental arteries.
- Geniohyoid: Origin: medial surface of mandible, Insertion: hyoid bone, Action: elevates hyoid bone, shortens floor of mouth, widens pharynx, Nerve supply: Hypoglossal nerve, Blood supply: Lingual artery (sublingual branch).
- Hyoglossus: Origin: hyoid bone, Insertion: lateral edges of tongue, Action: depresses and retracts tongue, Nerve supply: Hypoglossal nerve, Blood supply: Lingual artery
Summary Table
| Feature | FOM | Hard Palate | Soft Palate |
|---|---|---|---|
| Clinical Appearance | Reddish-pink, shiny, moist, compressible | Pink, firm, immobile | Reddish-pink, moist, elastic |
| Epithelium | Non-keratinized stratified squamous | Keratinized stratified squamous | Non-keratinized stratified squamous |
| Lamina Propria | Thick | Thick | Thick |
| Submucosa | Yes | No | Yes |
