Sub-lingual Salivary Gland
Identification Points:
1. Majority of acini are Mucous
2. Abundant Serous Demilunes
[absent in Parotid Gland]
3. Intercalated ducts are short/absent (not readily observed)
4. Non-striated Intra-lobular ducts [differentiating factor from other 2 salivary glands]
5. Abundant Interlobular Connective tissue septa

Description:
It is a mixed type of salivary gland with both serous and mucous acini, most of which are mucous and capped with serous demilunes, It is responsible for 2-5% of saliva secretion which is mucoid in nature.
It is smallest salivary gland, almond shaped located in the floor of oral cavity on either side of tongue.
