Study Notes
Salivary Glands Anatomy
- The parotid gland is the largest salivary gland, producing 100% serous saliva (watery and enzyme-rich), contributing 25% of total saliva.
- The submandibular gland produces a mixed saliva (serous and mucous), contributing to 60-65% of total saliva volume.
- The sublingual gland is the smallest of the major glands, predominantly producing mucous saliva, accounting for 5-10% of total saliva.
Parotid Gland
- Located below the external auditory meatus, between the mastoid process and the mandible.
- Stensen's duct opens near the maxillary second molar.
- Produces 100% serous saliva.
- Innervated by the autonomic portion of the glossopharyngeal nerve (CN IX) and the sensory portion of the auriculotemporal nerve.
Submandibular Gland
- Located in the submandibular fossa, below the mandible.
- Wharton's duct opens at the sublingual caruncle, near the lingual frenulum.
- Produces mixed saliva (serous and mucous).
- Innervated by the chorda tympani (branch of CN VII) for autonomic control and the lingual nerve for sensory input.
Sublingual Gland
- Located on the floor of the mouth, under the tongue.
- Bartholin's duct and Rivinus ducts open along the sublingual fold.
- Primarily produces mucous saliva.
- Innervated similarly to the submandibular gland, by the chorda tympani (CN VII) and the lingual nerve.
Salivary Gland Histology
- Epithelial tissue lines the ducts and produces saliva.
Salivary Gland Disorders
- Hyposalivation (Xerostomia): Dry mouth, caused by medications, radiation therapy, autoimmune disorders (e.g., Sjögren's syndrome), or dehydration.
- Obstructions (Sialolithiasis): Salivary stones block ducts, causing swelling and pain, often during meals.
- Radiotherapy effects: Can damage salivary glands, leading to xerostomia.
- Infections: Mumps can cause painful parotid swelling; nicotine stomatitis affects minor salivary glands due to heat from smoking.
- Sialosis: Non-inflammatory swelling of the parotid glands, linked to systemic conditions like diabetes or liver disease.
- Tumors (Neoplasms): Benign or malignant growths, like pleomorphic adenoma or salivary gland carcinoma.
