  2. Teeth • 32 adult/20 “milk” teeth • Medial/lateral incisor • Canine • 2 premolars • 3 molars

  3. Tooth Innervation

  4. Hard Palate • Palatine process maxillary bone • Horizontal plate palatine bone • > (3rd molar), < palatine foramina • Incisive foramen posterior nasal spine

  5. Lingual nerve crosses the submandibular duct twice!

  6. buccinator

  7. Salivary Glands

  8. parotid duct

  9. Muscles • Tensor veli • Levator veli • Palatoglossus • Palatopharyngeus • Musculus uvulae

  10. Extrinsic Tongue (L. lingua; G. glossa) Muscles

  11. XII lesion: tongue deviates to ipsilateral side

  12. Lymphatic Drainage • Gingivae and all teeth less the mandibular incisors drain into the submandibular lymph nodes • Tongue:

  13. Tongue Veins • Return to IJ directly or indirectly • Sublingual absorption

  14. Tongue Topography • Sulcus terminalis • Foramen cecum • Median sulcus and septum

  15. Papillae • Vallate • Foliate: lateral and poorly developed in humans; • Filiform: touch receptors (raspy); no taste buds • Fungiform:

  16. palatoglossal fold

  17. Taste • Tongue (Vallate, foliate, and fungiform) • Soft palate • Oral pharynx • Epiglottis
