Mandibular Salivary Gland
- Merocrine secretion
- Generally smaller than the parotid gland
- It is a moderately large gland in carnivores
- It is a large gland in herbivores
- Compact
- Located around angle of jaw
- Mandibular duct runs ventral to mucous membrane of floor of oral cavity, close to frenulum of tongue
- Duct opens at sublingual caruncle
Histology
- Tubulo-acinar gland
- Mucous cells (stain lighter)
- Serous demilunes (stain darker)
- Demilunes secrete into lumen by canaliculi between mucous cells
Species Differences
Carnivores
- Mainly mucous secretion in dog and cat
- Oval shape in canid
Herbivores
- Larger and deeper
