Salivary Glands and Submandibular Region Flashcards
where do the submandibular and sublingual glands sit
in the smooth bits of bone on the mandible called fossae
where does the submandibular duct originate
between the mylohyoid and hyoglossus muscles
what nerve loops around the submandibular duct
lingual nerve (CN V3)
what nerve loops around the submandibular duct
lingual nerve (CN V3)
what nerve loops around the submandibular duct
lingual nerve (CN V3)
what nerve loops around the submandibular duct
lingual nerve (CN V3)
how many orifices does the submandibular duct open into the oral cavity
three beside the frenulum
what is the position of the submandibular gland in relation to the mylohyoid muscle
sits partly above (deep) and below (superficial) connected at the posterior free end of the mylohyoid muscle
where is the deep part of the submandibular gland located
lateral to the root of the tongue on the floor of the oral cavity
what is the fibrous capsule of the submandibular gland continuous with
deep investing fascia
what is the blood supply to the submandibular gland
submental arteries via the facial artery
what is the venous drainage of the submandibular gland
submental veins (drain into facial and lingual veins)
where is the sublingual gland situated
between the mandible and hyoglossus muscle
what secretions does the sublingual gland produce
mucous
does the sublingual gland have a fibrous capsule
no
what is the blood supply to the sublingual gland
submental and sublingual arteries (via facial and lingual arteries)
what is the venous drainage of the sublingual gland
submental veins (into lingual and facial veins)
what are the preganaglionic fibres of the secretomotor innervation of the submandibular and sublingual glands
the chorda tympani (CN VII) or lingual nerve (CN V3)
what ganglion is associated with secretomotor innervation of the submandibular and sublingual glands
submandibular ganglion
what are the postganglionic fibres that give secretomotor innervation to the submandibular and sublingual glands
the lingual nerve (CN V£) or sometimes they dont travel in a nerve
describe the secretomotor innervation of parotid gland
glossopharyngeal nerve via lesser petrosal and tympanic nerves > otic ganglion > auriculotemporal nerve
what is the innervation of minor salivary glands above the oral fissure
greater petrosal nerve > pterygopalatine ganglion > palatine nerve
what is the innervation of minor salivary glands below the oral fissure
chorda tympani/ lingual nerve > submandibular ganglion > lingual nerve
what are minor salivary glands susceptible to
mucoceles - swelling due to blockage of associated ducts
what is a viral infection that causes painful swelling of the salivary glands
mumps
what could be the diagnosis for a lack of salivation, pain and swelling
salivary calculi
when does excess salivation occur
prior to vomiting
what are the main contents of the submandibular triangle
submandibular gland, lymoh nodes, parts of hypoglossal nerve, mylohyoid nerve and parts of the facial artery and vein and digastric
what are the main contents of the submandibular triangle
submandibular gland, lymph nodes, parts of hypoglossal nerve, mylohyoid nerve and parts of the facial artery and vein and digastric
what are the main contents of the submental triangle
submental lymph nodes and some small veins
what are the contents of the carotid triangle
carotid sheath, external carotid and some branches, parts of accessory and hypoglossal nerves, deep cervical lymph nodes
