T/F: The soft palate is mobile?
True
T/F: the soft palate elevates during swallowing to close the opening between the oro and nasopharynx
True
What is the median projection of the soft palate?
Uvula
What are the two lateral arches of the soft palate?
1) Palatoglossal arch
2) Palatopharyngel arch
What is contained within the palatoglossal arch?
1) Palatoglossal fold (superficial)
2) Palatoglossus muscle (deep)
What is contained within the palatopharyngeal arch
1) Palatopharyngeal fold (superficial)
2) Palatopharyngeus muscle (deep)
Where does the tonsilla fossa lie?
between the palatoglossal and palatopharyngeal arches (bilaterally)
What is contained within tonsillar fossa?
The Palatine Tonsils
Which muscle of the soft palate is NOT innervated by the vagus nerve via the pharyngeal plexus?
Tensor Veli Palatini- Innervated by the mandibular division of the trigiminal nerve (CN V)
Which muscle of teh soft palate opens the pharyngotympanic tube?
Tensor Veli Palatini
What is the Innervation for the palate?
Lesser Palatine Nerve
What is the blood supply of the soft palate?
Lesser Palatine and Facial arteries
How would one be able to diagnose damage to the vagus nerve within the oral cavity? What would cause this?
The uvula will be deviated to the opposite side of damage (ex, left vagus damage, uvula will go right)
-Often caused by trauma
