Study Notes
Salivary Glands
- Salivary glands are essential for oral health and can be affected by a range of medical conditions.
- Major salivary glands contribute 90% of total saliva volume.
- There are three pairs of major salivary glands: parotid, submandibular, and sublingual glands.
- Minor salivary glands are numerous and contribute the remaining 10% of saliva production.
- Salivary glands are supplied by the external carotid artery, with blood vessels and nerves entering at the hilum.
- Two capillary networks exist: one for secretory end pieces, and one for ducts.
- Saliva production is controlled by salivary nuclei in the brain, stimulated by taste, smell, and thoughts.
Disorders of Salivary Glands
- Hyposalivation (reduced saliva production) can be caused by medications, radiotherapy, autoimmune diseases, diabetes, and salivary stones.
- Obstruction, often caused by calcium deposits in the ducts, can lead to gland infection.
Parotid Glands
- Located below the ear, between the mastoid process and the posterior border of the ramus.
- Produce serous saliva (watery) and contribute 25% of total saliva volume.
- Innervation: Facial nerve
Submandibular Glands
- Found in the submandibular triangle, below the mandible.
- Produce mixed serous and mucous saliva.
- Contribute 60-65% of total saliva volume.
- Innervation: Facial nerve
Sublingual Glands
- Located beneath the tongue, near the floor of the mouth.
- Produce mainly mucous saliva
- Contribute 5-10% of total saliva volume.
- Innervation: Facial nerve
Salivary Gland Structure
- Three types of ducts: intercalated, striated, and excretory.
- Intercalated ducts, lined with cuboidal epithelial cells, guide saliva towards the striated ducts.
- Striated ducts, with a single layer of columnar epithelial cells, modify saliva.
- Excretory (terminal) ducts, lined with pseudostratified columnar epithelium, carry saliva into the oral cavity.
