Sublingual Salivary Gland
- Merocrine secretion
- Smaller than parotid gland
- 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.
Histology
- Tubulo-acinar gland
- Mucous cells (stain lighter)
- Serous demilunes (stain darker)
- Demilunes secrete into lumen by canaliculi between mucous cells
Species Differences
Ruminant and Pig
Equine
- Diffuse part is the only part of the sublingual salivary gland present
