Palate

Question 1

What structures are a part of the hard palate? What is the hard palate covered in? What is beneath this covering?

Answer 1

• Incisive foramen
• Greater/lesser palatine foramina
• Incisive papilla-Palatal rahpe
• Palatal rugae.Covered in keratinized mucosa, with palatal salivary glands just underneath.

Question 2

What is the pathway of nasopalatine nerve? Which branch is it?

Answer 2

Branch of V2
-Passes sphenopalatine foramen to nasal cana
l-Passes along superior nasal cavity to nasal septum
-Travels through incisive canal.

Question 3

What are the structures of the soft palate? Covered in what mucosa? Anterior zone and posterior zone of palatal submucosa contain what?

Answer 3

• Valve
• Uvula

Covered in keratinized mucosa.

Anterior=Contains fat
Posterior= Contains mucous glands.

Question 4

What are the margins of the soft palate?

Answer 4

• Anterior=Continuous with the hard palate
• Posteriorlaterally= forms superior portion of palatoglossal and palatopharyngeal folds.
• Posteriorly: Uvula hangs in space.

Question 5

What is the arterial supply of the soft palate? Through what structure?

Answer 5

• Greater palatine (via palatine foramen)
• Lesser palatine (Via palatine foramen)
• Sphenopalatine (Via inscisive foramen)

Question 6

What are the muscles of the soft palate?

Answer 6

1. Tensor veli palatini
2. Levator veli palatini
3. Palatopharyngeaus
4. Palatoglossus
5. Musculus uvulae

Question 7

What is the O, I, A, and N of the tensor veli palatini? Special characteristics?

Answer 7

O: Auditory tube, scaphoid fossa of sphenoid
I: Palatine aponeurosis
A: Tenses soft palate, pulls soft palate laterally, opens auditory tube.
N: Medial pterygoid of V3

Loops around the pterygoid hamulus and acts as a pully.

Question 8

What is the O, I, A, and N of musculus uvulae?

Answer 8

O: Posterior nasal spin, palatine aponeurosis
I: Muscle of opposite side (itself)
A: Elevates uvula and pulls laterally
N: CNX, via pharyngeal plexus

Question 9

What is the O, I, A, and N of palatoglossus?

Answer 9

O: Anterior surface of soft palate, palatine aponeurosis
I: Lateral tongue
A: Elevates tongue, depresses soft palate. (Narrows isthmus of fauces)
N: CNX, via pharyngeal plexus

Question 10

What is the O, I, A, and N of the palatopharyngeus?

Answer 10

O: Posterior border of hard palate, palatine aponeurosis.
I: Pharynx
A: Elevates pharynx, helps close nasopharynx
N: CNX, via pharyngeal plexus

Question 11

What is the order anterior to posterior of the pillar of fauces and palatine tonsils? What connects the two fauces?

Answer 11

1. Palatoglossal arch/fold
2. Palatine tonsil
3. Palatopharyngeal arch/foldIsthmus of fauces connects the two arches/folds.

Question 12

Soft palate attaches to the tongue and pharynx via what structures?

Answer 12

Tongue=Via palatoglossal arches

Pharynx= Via palatopharyngeal arches
