Study Notes
Salivary Glands
- Parotid gland: Largest salivary gland located below external auditory meatus (ear), between mastoid process and posterior body of ramus. Secretes 25% of total saliva volume, all of which is serous.
- Submandibular gland: Located between body and mandible, and mylohyoid muscle. Secretes 60-65% of total saliva volume, which is a combination of serous and mucous.
- Sublingual gland: Located at the floor of the mouth in the sublingual fossa. Secretes 5-10% of total saliva volume, primarily mucous.
- Minor salivary glands: Numerous small groups of secretory units located throughout the mouth. Secretes less than 10% of total saliva volume, mainly mucous saliva.
Salivary Glands - Ducts and Innervation
- Parotid gland: Stensen's duct or parorid duct is 5cm long and opens into the oral cavity in the buccal region near the upper first molar.
- Submandibular gland: Wharton's duct is 5cm long and opens lateral to the lingual foramen.
- Sublingual gland: Has 10-20 smaller ducts called the rivinus that open along the sublingual fold.
- Minor salivary glands: Secretory units open directly into the mouth via short ducts.
- Parotid gland: Innervated mostly by the glossopharyngeal nerve (autonomic), and also by the auriculotemporal nerve (sensory).
- Submandibular gland: Innervated by the chorda tympani (branches off facial nerve) and also by the lingual branch of the inferior dental nerve.
- Sublingual gland: Innervated by the chorda tympani (branches off the facial nerve) and also by the lingual branch of the inferior dental nerve.
- Minor salivary glands: Innervated by the parasympathetic nervous system, mainly, and also the sympathetic nervous system.
