Flashcards in Lab 24 Palate and Nasopharynx Deck (36):
1

What is the best place to look for the palatine nerves and vessels? Where will we trace them?

the greater and lesser palatine foramen because they are largest here, trace anteriorly

2

Posterior to the greater palatines, identify the ____ nerve and _____ artery that supply the soft palate.

lesser palatine for both

3

The palate is covered by _____, which contains numerous _______ on the oral surface.

mucosa, contains numerous mucous glands (palatine glands)

4

What is deep to the palatopharyngeal fold? ;)

palatopharyngeus muscle

5

What are the anterior, posterior, and lateral boundaries of the tonsillar bed for the palatine tonsil?

anterior- palatoglossal fold
posterior- palatopharyngeal fold
superior pharyngeal constrictor- lateral

6

What branch of trigeminal is found within the pterygopalatine fossa?

maxillary nerve (V2)

7

What passes through the inferior orbital fissure to enter the infraorbital canal and then through the infraorbital foramen?

infraorbital artery

8

The maxillary artery can be followed to the pterygomaxillary fissure where it gives off 3 branches. Name them.

Sphenopalatine artery, descending palatine artery, infraorbital artery

9

Conical-shaped posterior end of the soft palate is called what?

uvula

10

What are the attachments of the levator veli palatini?

pharyngotympanic tube, temporal bone, and palatine aponeurosis

11

The palate consists of 2 portions. What are they?

The hard palate- anterior 2/3
The soft palate- posterior 1/3

12

What is a terminal branch of the maxillary artery?

the descending palatine artery of course

13

What gives the soft palate its strength?

palatine aponeurosis

14

What passes through pterygopalatine fossa and then through the sphenopalatine foramen to enter the nasal cavity?

sphenopalatine artery

15

What is deep to the salpingopharyngeal fold? ;)

salpingopharyngeus muscle

16

What is a slight bulge anterior to the opening of the pharyngotympanic tube? This covers the tensor veli palatini!!!

salpingopalatine fold

17

The greater palatine nerve should be _____ and more _____ than the lesser.

larger and more anterior

18

The bulge superior to the opening of the pharyngotympanic tube is called what?

torus tubarius

19

What nerve courses from the foramen rotundum towards the inferior orbital fissure?

the maxillary nerve

20

What muscle enters the pharynx between the superior and middle constrictors with the glossopharyngeal nerve?

stylopharyngeus- also lies anterior and parallel to the palato- and salpingopharyngeus muscles, then blends with them inferiorly

21

The palate forms the floor of the _____ cavity and the roof of the _____ cavity.

nasal, oral

22

What lies lateral to the medial plate of pterygoid process? Where does it originate?

-tensor veli palatini
-originates on the scaphoid fossa between the medial and lateral plates, its tendon wraps around the pterygoid hamulus to form the palatine aponeurosis

23

What 3 things are found in the greater palatine canal?

the greater palatine nerve, lesser palatine nerve, and the descending palatine artery

24

The ridge in the floor of the sinus indicates the location of the _____ canal. A nerve is found here entering the pterygopalatine fossa from the ____.

Pterygoid canal with the nerve of pterygoid canal

posterior

25

What does the maxillary nerve give off before reaching the infraorbital fissure?

the infraobrital nerve

26

Muscles attaching to the posterior 2/3 of the soft palate allow for what?

movement

27

This muscle is found from the cartilage of the pharyngotympanic tube and blends with the palatopharyngeus to attach to the thyroid cartilage and pharyngeal wall.

salpingopharyngeus

28

What is the bulge inferior to the opening of the pharyngotympanic tube and covers the levator veli palatini?

torus levatorius

29

The nerve of the pterygoid canal is found between the anterior wall of the ____ and its attachment to the ______.

sphenoidal sinus

pterygopalatine ganglion

30

The 5 muscles of the soft palate are innervated by the _____ nerve while the tensor veli palatini is innervated by the ______ nerve.

What foramen is at the posterior end of the middle nasal concha?

sphenopalatine foramen

32

What is deep to the palatoglossal fold? ;)

33

What is attached to the palatine aponeurosis, hard palate and inferiorly to the thyroid cartilage and pharyngeal wall?

palatopharyngeus muscle

34

What nerve passes between the superior and middle constrictors to enter the tonsillar bed? Where is this usually found in relation to the palatine tonsil?

glossoharyngeal nerve (IX)
inferior margin

35

What is the gap superior to the superior pharyngeal constrictor partially filled with? What passes through the gap?
