1. SALIVARY GLANDS AND PANCREAS

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

14. SUBMANDIBULAR GLAND

15. SUBLINGUAL GLAND

16. COMPARISION

17. PANCREAS

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

20. CAPSULE & SEPTA

21. EXOCRINE PANCREAS

22. CENTROACINAR CELLS

23. CENTROACINAR CELLS

24. DUCT SYSTEM

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

26. INTERCALATED DUCT
Add bicarbonate and water to the exocrine secretion

28. EXCRETORY DUCT

29. ENDOCRINE PANCREAS

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

31. SCHEMATIC DRAWING

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