SALIVARY GLANDS AND PANCREAS Dr Iram Tassaduq
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.
MAJOR SALIVARY GLANDS
STRUCTURE OF GLAND
MYOEPITHELIAL CELLS Contractile cells Lie between basal plasma membrane of epithelial cells and basal lamina of epithelium Move secretory product
DUCT SYSTEM
INTERCALATED DUCT It leads from acinus
STRIATED DUCT Striations are produced due to in folding of basal plasma membranes of columnar cells forming duct
INTERLOBULAR DUCT
EXCRETORY DUCT
DUCT SYSTEM
OPENNING OF EXCRETORY DUCT
SUBMANDIBULAR GLAND
SUBLINGUAL GLAND
COMPARISION
PANCREAS
PANCREAS Compound tubulo alveolar gland Striated ducts absent Intercalated duct cells do not contain secretory granules
CAPSULE & SEPTA
EXOCRINE PANCREAS
CENTROACINAR CELLS
CENTROACINAR CELLS
DUCT SYSTEM
ZYMOGEN GRANULES Contain variety of digestive enzymes like exo and endopeptidases, Lipases and nucleolytic enzymes
INTERCALATED DUCT Add bicarbonate and water to the exocrine secretion
EXCRETORY DUCT
ENDOCRINE PANCREAS
ISLETS OF LANGERHANS Islets constitute 12% of total volume Polyhedral cells are arranged in short irregular cords surrounded by network of fenestrated capillaries
SCHEMATIC DRAWING
CELLS OF ISLETS Most abundant in tail A cells secrete Glucagon B cells secrete Insulin most numerous D cells secrete Somatostatin
