Study Notes

Salivary Glands

Major salivary glands include:
Parotid gland
Submandibular gland
Sublingual gland
Intercalated ducts in the duct system of salivary glands are lined with cuboidal cells.

Composition of Secretions

Serous acini produce secretion rich in enzymes, specifically:
- Water
- Electrolytes
- Enzymes (e.g., amylase, lipase)
Mucous acini produce mucin, a thick, protective substance.

Functions and Characteristics

The parotid gland produces the highest percentage of salivary output.
The sublingual gland is not capsulated.
Serous acini secrete enzymes, while mucous acini secrete mucin.
Mucous acini with a cap (demilunes) function in mucin production.
The functional element of the salivary glands' microscopic structure is the acinus.
The supporting element of the salivary glands' microscopic structure is the connective tissue.

Minor Salivary Glands

Minor salivary glands produce a small percentage (about 10%) of salivary output.
Most minor salivary glands produce mucous secretions.

Salivary Gland Structure

The structure that divides the salivary glands into lobes and lobules is the connective tissue.
Mucoserous (mixed) acini contain both mucous and serous cells, and function in producing both mucin and enzymes.
Seromucous glands produce both serous and mucous secretions.
The functional element of the salivary glands' microscopic structure is the acinus, which contains serous or mucous cells.
