  5. Division of The mouth cavity: a-vestibule b- mouth proper

  6. Vestibule of the mouth Boundaries Communication Lateral wall Opening of parotid duct

  7. Mouth proper Roof of mouth Floor of mouth

  8. Floor of the mouth Frenulum of the tongue Plicafimbriata Sublingual fold

  9. Mucous membrane of the mouth Is strongly attached to alveolar periosteumSensory inervation of the mouth Roof Floor cheek

  10. Deciduous Eruption Chart

  11. Permanent Eruption Chart

  12. The teeth Deciduous teeth Permanent teeth: number and eruption

  13. teeth

  14. The tongue

  15. Blood supply of tongue

  16. Intrinsic muscles of the tongueall muscles of the tongue are innervated by hypoglossal nerve except palatoglossus innervated by cranial root of accessory nerve.

  17. Extrinsic Muscles of the tongue

  18. Genioglossus muscle

  19. Hyoglossus, Styloglossus, palatpglossus

  20. Lymph drainage Submental lymph node Aubmandibular lymph node Deep cervical lymph node

  21. Sensory inervation

  22. The palate Hard palate soft palate

  23. The hard palate

  24. uvula

  25. Palatine aponeurosis

  26. Muscles of soft palate

  27. Musculus uvulae

  28. Nerve supply

  29. Blood supply

  30. Palatoglossus and palatopharyngeal folds

  31. Submandibular salivary gland • Site: it lies in submandibular (digastric triangle) • Parts: divided into two parts by mylohyoid muscle superficial part: • Shape: wedge shape with • superficial surface cover by skin and fascia • Lateral surface related to the mandibule • Medial surface related to the floor of the mouse Deep part: • Lies deep to mylohyoid muscle • Related to lingual and hypoglossal nerve Submandibular duct • Emerge from the anterior end of the deep part • Open at side of the frenulum of the tongue

  32. Sublingual salivary glangs • Is the smallest of the three main salivary glands • It has both serous and mucous acini • Site: related to sublingual fossa of mandibular under cover of mucous membrane of the mouth (sublingual fold) • Ducts: open into the floor of the mouse (8-20)

  33. Site: superficial surface

  34. Parts: surface of superficial part

  35. Parts: deep part

  36. duct

  37. opening

  38. Nerve supply

  39. PAROTID GLAND • Definition • Shape • site

  40. Surfaces and Ralation of parotid gland

  41. Structure inside parotid gland

  42. Parotid gland and facial nerve

  43. Parotid duct

  44. Work sheetStructure inside parotid gland • A) Auriculo-temporal n. • b) Ext. carotid a → divides (behind the neck of mandible) into maxillary and superficial temporal arteries • c) Retromandibular v. • d) Facial n.→ divides into 5 terminal brs. • e) Deep parotid L.Ns.

  45. Nerves of the gland • Parasympathetic (secretomotor): The preganglionicfs. reach the otic ganglion • from the lesser petrosal n. (br. from the glossopharyngeal n.) • The postganglionic fs. Arising from the otic ganglion and • Carried to the gland by the auriculo-temporal n.
