Sublingual Gland

The sublingual gland is one of the major salivary glands. It is major mucous (65%) and minor serous (35%).

Stroma - the connective tissue component of the gland.
- - connective tissue that encapsulates the gland.
- - connective tissue divides the gland into lobules.
Parenchyma - the functional component of the gland that consists of secretory cells and ducts
- (rich in carbohydrates) - are lightly stained with a "foamy" appearance (the mucous has been extracted) and are the major portion of the gland.
- (rich in proteins) - are darkly stained and are a minor portion of the gland.
- - acini of light stained mucous cells are surrounded by the darkly stained serous cells.
- Intralobular Ducts - two types are found within lobules:
  - Intercalated Ducts - the smallest ducts (low cuboidal) that insert into and drain individual acini.
  - - arise from intercalated ducts.
- (or extralobular ducts) - found outside of lobules.
- - maybe simple columnar, pseudostratified columnar or stratified cuboidal epithelium. are a common feature of sublingual ducts.
