  1. SALIVARY GLANDS AND PANCREAS Dr Iram Tassaduq

  2. MINOR SALIVARY GLANDS The minor salivary glands are located in the submucosa of different parts of the oral cavity. They include the lingual, labial, buccal, molar and palatine glands.

  3. MAJOR SALIVARY GLANDS

  4. STRUCTURE OF GLAND

  5. Myoepithelial cells • Contractile cells • Lie between basal plasma membrane of epithelial cells and basal lamina of epithelium • Move secretory product

  6. DUCT SYSTEM

  7. Intercalated Duct • It leads from acinus

  8. Striated duct • Striations are produced due to in folding of basal plasma membranes of columnar cells forming duct

  9. INTERLOBULAR DUCT

  10. EXCRETORY DUCT

  11. DUCT SYSTEM

  12. OPENNING OF EXCRETORY DUCT

  13. SUBMANDIBULAR GLAND

  14. SUBLINGUAL GLAND

  15. COMPARISION

  16. PANCREAS

  17. PANCREAS • Compound tubulo alveolar gland • Striated ducts absent • Intercalated duct cells do not contain secretory granules

  18. CAPSULE & SEPTA

  19. EXOCRINE PANCREAS

  20. CENTROACINAR CELLS

  21. CENTROACINAR CELLS

  22. DUCT SYSTEM

  23. ZYMOGEN GRANULES • Contain variety of digestive enzymes like exo and endopeptidases, Lipases and nucleolytic enzymes

  24. INTERCALATED DUCT • Add bicarbonate and water to the exocrine secretion

  25. EXCRETORY DUCT

  26. ENDOCRINE PANCREAS

  27. ISLETS OF LANGERHANS • Islets constitute 1-2% of total volume • Polyhedral cells are arranged in short irregular cords surrounded by network of fenestrated capillaries

  28. SCHEMATIC DRAWING

  29. CELLS OF ISLETS • Most abundant in tail • A cells secrete Glucagon • B cells secrete Insulin most numerous • D cells secrete Somatostatin
