Salivary Gland Anatomy Flashcards
what part of the NS controls salivation
autonomic NS
are salivary glands exocrine or endocrine
EXOcrine thus have ducts associated with them
name the 3 major paired glands
parotid, sublingual, submandibular
location of parotid gland
right in front of ear
behind the mandible
position of parotid ducts
through the MASSETER, pierces the BUCCINATOR, opens up on the cavity on cheek opposite to U7
blood supply of parotid
branches of EXTERNAL carotid artery
nerve supply of paortid
glossopharyngeal nerve (9)
synapses at OTIC GANGLION
post-ganglionic nerve fibres travel via the AURICULO-TEMPORAL NERVE (V3 of trigeminal nerve)
insert into parotid gland
does facial nerve innervate the parotid
no simply passes through the parotid on its way to facial muscles but DOES NOT innervate it
location of submandibular gland
under the mandible (one on either side)
how many submandibular duct are there
ONE discrete duct
nerve supply of submandibular and sub-lingual
FACIAL nerve (7) branch called CHORDA TYMPANI and branch of LINGUAL nerve (branch of V3) both synapse at the SUB-MANDIBULAR GANGLION the post-synaptic ganglionic fibres insert into submandibular and sublingual glands
location of sub-lingual glands
under tongue
anterior to sub-mandibular duct
what are glands of von ebner
minor salivary glands
location of glands is on circumvallate papillae on the dorsal surface of the tongue
serous secretion
nerve supply: glossopharngeal nerve
what are ‘secretomotor cells’
nerve fibres which cause salivary gland secretion
