Sublingual and Submandibular glands Flashcards
Weight of sublingual gland
3-4g
Smallest salivary gland
Sublingual gland
Shape of sublingual gland
Almond shaped
Borders of sublingual gland
Medially: Geniohyoid Hyoglossus
Laterally: Mandible
Inferiorly: Mylohyoid muscle
Situation or location of the sublingual gland
It lies above the mylohyoid
below the mucosa of the floor of the mouth
medial to the sublingual fossa of the mandible
and lateral to the genioglossus
The gland forms a groove on the medial surface of
the mandible called
sublingual fossa
What passes medial to the sublingual gland
submandibular duct and the lingual nerve
The sublingual glands unite anteriorly around
Lingual frenulum
The superior aspect of the union of the sublingual glands forms
Sublingual fold
Secretions from the sublingual glands drain
into the oral cavity by
minor sublingual ducts
How many excretory ducts are found per sublingual gland
8-20 excretory ducts
sublingual fold extends to join the sublingual
papillae at
Midline
sublingual duct of bartholin adheres to
the submandibular duct on its medial
side
Major sublingual duct of bartholin is located where
at the inferior aspect of the
sublingual gland
Blood supply of sublingual glands
Arterial supply: Sublingual and submental arteries (branches of lingual and facial arteries)
Venous drainage: Sublingual and submental veins
Innervation of sublingual glands
It receives parasympathetic input via the chorda tympani branch of facial nerve via the submandibular ganglion
The Wharton’s duct begins at
the hilum of the
submandibular gland
Second largest salivary gland
Sub mandibular gland
Where are the submandibular gland located
in the posterior part of the digastric/ submandibular
triangle
the primary excretory
duct for the submandibular gland is
Wharton duct
Where does the wharton duct drain the submandibular gland
at the sublingual caruncle
Blood supply of submandibular gland
Arterial supply: Submental and sublingual artery
Venous drainage: Common facial and sublingual vein
The submandibular gland travels around the posterior portion of what muscle and
opens into the oral cavity at
Mylohyoid
Sublingual carancule
Lymphatic drainage of submandibular glands
Submandibular nodes and they drain into the deep cervical lymph nodes
Weight of submandibular glands
15-20g
Innervation of submandibular glands
Receive parasympathetic input via chorda tympani branch of facial nerve
