Salivary Glands - Location, Opening and Secretions
[BDC H&N 4th ed 165]
Gland: Parotid
Location: Below external acoustic meatus between the ramus of mandible and the sterocleidomastoid. It is the largest of all the salivary glands.
Duct opening: Stensons duct - After piercing the buccinator opens into the vestibule of mouth opposite the crown of maxillary 2nd molar.
Secretion: Purely serous
Gland: Sub-mandibular
Location: Roughly 'J' shaped salivary gland, situated in the anterior part of digastric triangle. The gland is divided into large superficial and small deep parts by mylohyoid muscle.
Duct opening: Wharton's duct opens on the floor of mouth, on the summit of the lingula papilla, at the side of frenulum of the tongue.
Secretion: Mixed and predominantly serous
Gland: Sublingual gland
Location: Smallest of the three salivary glands. It is situated above the mylohyoid below the mucosa of the floor of the mouth.
Duct opening: Bartholins duct - 10-15 ducts emerge from the gland. Most of them open directly into the floor of mouth on the summit of sublingual fold. A few of them join the submandibular duct.
Secretion: Mixed and predominantly mucous.
