2. 分泌量: Submandibular> Parotid> sublingual

3. Parotid Gln. -> Stenson's Duct   ;   Submandibular -> Warthin's Duct

4. Serous: parotid ; Mucus: sublingual ; Mix: submandibular

5. Parotid: CN9->Jacobson n.->lesser petrosal n.->Otic gang.->auriculotemporal n.

    Submandibular: CN7->chorda tympany->submandi. gang.->Gln.

    Sublingual:CN7->chorda tympany->sublingual. gang.->Gln.
