The hard and soft palate Flashcards
what bones make up the hard palate
palatine parts of maxilla mainly and also 2 palatine bones that complete the posterior part
where is the soft palate
muscle and connective tissue handing from posterior border of hard palate
the small glands embedded into the mucosa covering the hard palate produce mucous - what are they innervated by?
facial nerve CN VII
what surface markings are found at the front of the hard palate
transverse palatine folds (rugae)
what is the line down the middle of the palate called
palatine raphe
what nerves and vessels supply the palate
greater palatine
where does the greater palatine artery arise
pterygopalatine fossa
the greater palatine artery is a branch of what
3rd part of the maxillary artery
the greater palatine artery descends in what to enter the palate via what
descends in the palatine canal to enter the palate via the greater palatine foramen
the greater palatine artery descends in the palatine canal to enter the palate via the
greater palatine foramen
the greater palatine nerves are branches of what
maxillary division of the trigeminal nerve
the greater palatine nerves are branches of the maxillary division of the trigeminal nerve from what ganglion
from the pterygopalatine (sphenopalatine) ganglion
the greater palatine nerves and vessels descend in what and enter via what
palatine canal
greater palatine foramen
what modality is CNV2
sensory
what branches of the greater palatine vessels and nerves pass posteriorly to supply the soft palate
lesser palatine vessels and nerves
the lesser palatine vessels and nerves are branches of what and supply what
branches of the greater palatine and supply the soft palate
blood to the palate is from
maxillary artery
sensory to the palate is from
CN V2
what is the name of the nerve at the anterior most point of the palate
nasopalatine nerve
what is the palatine aponeurosis function
attaches to the hard palate - tough connective tissue and helps to strengthen the soft palate and provide a site for muscle attachment
there are _ muscles that move the soft palate in response to food/fluid in the oral cavity

what happens if the soft palate is touched unexpectedly
gag reflex - muscles of the pharynx try and expel the unexpected item
what is the sensory arm of the gag reflex
glossopharyngeal nerve
what are the muscles of the soft palate
