    7. Salivary Gland Tumor
  2. Anatomy
    1. Minor Salivary Glands
      1. Hundreds throughout mouth
      2. Line the mucosa of the lips, Tongue and oropharynx
    2. Major Salivary Glands (3 on each side of face)
      1. Parotid Gland (cheek)
      2. Submandibular Gland (under angle of the jaw)
      3. Sublingual Gland (under Tongue)
  3. Physiology
    1. Saliva function
      1. Controls oral pH
      2. Assists with food intake
        1. Lubricates food bolus
        2. Contains amylase for carbohydrate digestion
      3. Mouth cleansing and Oral Hygiene
        1. Saliva limits oral pathogen growth
        2. Reduces oral odor (halitosis)
    2. Differential Saliva production by glands
      1. Unstimulated Salivation (Salivary Gland at rest)
        1. 1.5 Liters produced per day (basal rate)
        2. Major Salivary Glands: 90% of Saliva produced
        3. Submandibular and Sublingual Glands: 70% of Saliva
      2. Stimulated Salivation
        1. Saliva production increases 5 fold
        2. Parotid Gland produces majority of Saliva
    3. Innervation
      1. Parasympathetic innervation to major Salivary Glands
        1. Otic Ganglion fibers supply Parotid Gland
        2. Submandibular Ganglion supplies other major glands
      2. Sympathetic innervation promotes Saliva flow
        1. Stimulates muscle contractions at Salivary ducts
  4. Associated Conditions: Pathologic Salivary Gland Conditions
    1. Sialadenitis (Salivary Gland Infection)
    2. Sialolithiasis (Salivary duct calculus)
    3. Ptyalism or Sialorrhea (Drooling)
    4. Xerostomia (Decreased Saliva Secretion)
    5. Salivary Gland Tumor
    6. Salivary Gland Enlargement

saliva (C0036087)

Definition (NCI_NCI-GLOSS) The watery fluid in the mouth made by the salivary glands. Saliva moistens food to help digestion and it helps protect the mouth against infections.

Definition (NCI_CDISC) A clear liquid secreted into the mouth by the salivary glands and mucous glands of the mouth; moistens the mouth and starts the digestion of starches. (NCI)
Definition (MSH) The clear, viscous fluid secreted by the SALIVARY GLANDS and mucous glands of the mouth. It contains MUCINS, water, organic salts, and ptylin.

Salivary Glands (C0036098)

Definition (FMA) Lobular organ the parenchyma of which consists of glandular acini which communicate the oral cavity. Examples: parotid gland, sublingual gland, lingual salivary gland.
Definition (MSHCZE) Žlázy v ústech vylučující sliny. Jedná se o tři páry slinných žláz – (PAROTIS – příušní žláza, PODJAZYKOVÁ SLINNÁ ŽLÁZA a PODČELISTNÍ SLINNÁ ŽLÁZA). slinné žlázy – žlázy tvořící sliny (viz saliva, salivace). K velkým s. ž. patří tři párové žlázy: žláza příušní (glandula parotis), žláza podčelistní (glandula submandibularis) a žláza podjazyková (glandula sublingualis). Kromě toho existují v dutině ústní i drobné s. ž. (glandulae labiales, buccales, atd.) (cit. Velký lékařský slovník online 2012, http://lekarske.slovniky.cz/ )
Definition (UWDA) Lobular organ the parenchyma of which consists of glandular acini which communicate the oral cavity. Examples: parotid gland, sublingual gland, lingual salivary gland.
Definition (NCI_NCI-GLOSS) A gland in the mouth that produces saliva.
Definition (NCI_CDISC) An exocrine gland that secretes saliva. Salivary glands are mostly located in and around the oral cavity.
Definition (NCI) An exocrine gland that secretes saliva. Salivary glands are mostly located in and around the oral cavity.
Definition (MSH) Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).
Definition (CSP) any of the three pairs of glands that secrete saliva in the mouth and aid in digestion.
