2. Large salivary glands 3 pairs: submandibular, sublingual, parotid
tubulo-acinar rammified glands
general organization :

Parenchyme:
serous, mucous or mixed acini
excretory ducts
3. Secretory portion – cellular types Serous cells:
Round, euchromatic nucleus;
double stain cytoplasm : basal pole - basophilic, apycal pole - acidophilic
Organized in acini or serous demilunes
Mucous cells:
Basal, flattened nucleus;
pale cytoplasm (acidophilic);
Organized in tubes or acini
