  2. Parts of the body

  3. Regions Th12/L1

  4. Regions

  5. Supra-andinfrahyoidmuscles

  6. Cervicaltrigone Submentaltrigone Submandibulartrigone Carotidtrigone Omoclaviculartrigone

  7. Cervicaltrigone Submentaltrigone: lymphnodes Submandibulartrigone: submandibulargland lateralgroove of thetongue (nerves) Carotidtrigone: carotidsheath (commoncarotidartery internaljugularvein vagusnerve) Supraclaviculartigone: 2 parts: omotrapezoidtrigone: cervicalplexus omoclaviculertrigone: brachialplexus subclavian art. apex of thelung

  8. Cervicaltrigones omoclaviculartrigone: brachialplexus subclavial art. and vein. apex of thelung carotidtrigone

  12. Teeth

  13. Teeth dentes permanentes dentesdecidui dentes permanentes

  15. crown (coronadentis) neck gingiva root (radix) pulp (pulpa) bone

  16. enamel dentine cementum periodontum

  17. Innervation of the teeth Trigeminal ganglion Maxillary nerve Inf. alveolar nerve (mandibular n.)

  18. Tongue root sulcusterminalis palatine tonsil palatine tonsil lingual tonsils circumvallate papillae foliate papillae apex fungiform papillae filiform papillae

  19. Taste sensation green: bitter blue: sour red: salty orange: sweet

  20. Innervation of the tongue Sensory innervation: general: lingual n. (V./3) – anterior 2/3 glossopharyngeal n. (IX.) – posterior 1/3 vagus n. (X.) – the most posterior part taste: chorda tympani (VII.) – anterior 2/3 glossopharyngeal n.(IX.) – posterior 1/3 Motory innervation: hypoglossal n. (XII.)

  21. Salivary glands I. parotis parotid duct Opens: vestibule, upperrow of theteeth (2nd molar)

  22. Salivary glands II. parotis submandibular gland

  23. Sublingual region frenulum of the tongue sublingual gland
