Salivary Glands And Submandibular Region Flashcards
Name the three major paired salivary glands
Parotid, submandibular and sublingual
Which salivary gland wraps around the free edge of the mylohyoid muscle
Submandibular gland
What kind of secretions does the parotid gland have
Mixed
Which kind of fascia is the fascial capsule of the submandibular gland continuous with
Deep investing cervical fascia
Where do the submandibular ducts open into the oral cavity
They open into small lingual papilla next to the lingual frenulum of the tongue
What is the blood supply to the submandibular glands
The submental artery
What is the venous drainage of the submandibular ducts
The submental veins to the lingual and facial veins
What is the main secretion from the sublingual gland
Mostly mucous
Where does the sublingual gland lie
Floor of mouth between the mandible and the hyoglossus muslce
Does the sublingual gland have a fibrous capsule`
No
Which nerve does the submandibular gland lie on
The Lingual nerve
Discuss the parasympathetic innervation to the salivary glands - secretomotor to produce saliva
Preganglionic Sympathetic fibres travel to the submandibular ganglion from the chorda tympani via the lingual nerve.
Postganglionic parasympathiec fibres then travel in the lingual nerve to the submandibular gland to the sublingual gland or travel directly to the submandibular and sublingual gland not in a nerve
What condition of the salivary glands can sympathetic innervation lead to
Vasoconstriction and reduction in volume of saliva can lead to DRY MOUTH
What are the two innervation of the minor salivary glands and how can we differentiate
All glands above the level of the oral fissure are innervated by the greater petrosal nerve
All glands below level of oral fissure innervated by chorda tympani cn7
Which ganglion is on the greater petrosal nerve
The ptergopalatine gang alison
