2) Palatoglossus muscle (deep)

6

What is contained within the palatopharyngeal arch

7

Where does the tonsilla fossa lie?

between the palatoglossal and palatopharyngeal arches (bilaterally)

8

What is contained within tonsillar fossa?

The Palatine Tonsils

9

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)

Tensor Veli Palatini

11

What is the Innervation for the palate?

Lesser Palatine Nerve

12

What is the blood supply of the soft palate?

Lesser Palatine and Facial arteries

13

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
