MAJOR SALIVARY GLANDS



Sublingual Salivary Gland

  • Merocrine secretion
  • Consists of monostomatic compact part drained by a single duct. Located over rostral mandibluar gland in dog. Duct runs with mandibluar gland duct and opens at the sublingual caruncle.
  • Consists of polystomatic diffuse part drained by numerous smaller ducts. Thin strip below mucosa of the floor of oral cavity and duct opens beside the frenulum.

  • Serous demilunes (stain darker)
  • Demilunes secrete into lumen by canaliculi between mucous cells
