Flashcards in Palate Deck (28):
What forms the hard palate?
Palatine process of maxillae, horizontal processes of palatine bones
What is midline immediately posterior to the incisors?
Where are the greate and lesser palatine foramina found?
Inferior margin of the perpendicular palatine bone
What forms ridges in the muscosa of the anterior hard palate?
Transverse palatine folds (rugae)
Found deep to the mucosa in both the hard palate and oral portion of the soft palate
Musus-secreting palatine glands
Naming of the mucus on the superior surface of the soft palate
Naming of the mucus on the inferior surface of the soft palate
What is the soft palate conposed of?
Connective tissue and muscle covered in mucosa
Attaches to the posterior margin of the hard palate and forms the connective tissue sheet of the soft palate
What makes up the bulk of the soft palate?
Where are the palating tonsils located?
Between the palatoglossal and palatopharyngeal arches
During swalloing, how is food prevented from entering the nasopharynx?
Soft palate elevates against the posterior wall of the pharynx
Tendon of the tensor veli palatini
passes inferiorly around hamulus of the medial pterygoid plate and blends with the palatine aponeruosis
2 muscles that attach to the auditory tube
Tensor veli palatini, levator veli palatini
Elevates the soft palate
Levator veli palatini
Pulls the tingue and soft palate toward each other during swallowing
Draws the pharynx superiorly/anteriorly/medially during swallowing
Shortens the uvula
What muscle is NOT innervated by the motor nerve of vagus nerve?
Tensor veli palatini
What innervates the tensor veli palatini?
What innervates the sensory of the palate?
Branches of V2 via pterygopalatine
Preganglionic parasympathetic innervation of pterygopalatine ganglion
Facial nerve via greater petrosal nerve
Postganglion parasympathetic innervation of pterygopalatine ganglion
To mucosa for secretion
Postganglion sympathetic via superior cervical ganglion to palate
Vasomotor to blood vessels of palate
Blood supply of palate origin
3rd division of maxillary artery
Portion of facial artery that supplies the palate
Ascending palatine branch
