Q

What does the palatopharyngeus do?

A

it will pull the wall upward, forward, and medial to shorten the pharynx and it also constricts the oropharyngeal isthmus by adducting the posterior pharyngeal pillars

Q

Where does the levator palati extend?

A

from under the surface of the petrous temporal bone down into the palatine aponeurosis

24
Q

What does the levator palati do?

A

elevator of the soft palate

25
Q

Where does the tensor palati extend?

A

from the scaphoid fossa at the base of the medial pterygoid plate around the pterygoid hamulus to insert into the lateral aspects of the palatine aponeurosis

26
Q

What does the tensor palati do?

A

unilaterally it pulls the soft palate to one side; bilaterally it will tense, tighten, and depress

27
Q

What is the motor innervation of all the palatal musculature (one exception)?

A

pharyngeal plexus

28
Q

What is the one exception to the innervation of the palatal musculature?

A

the tensor palati and it is innervated by V3

29
Q

What does the pharynx lie anterior to?

A

cervical vertebral column

30
Q

What is the pharynx posterior to?

A

the nasal and oral cavities and the larynx

31
Q

What parts is the pharynx divided in to?

A

nasopharynx, oropharynx, laryngopharynx

32
Q

What can the pharynx be described as?

A

a fibromuscular tube with a number of anterior deficiencies in its wall

33
Q

The superior end of the tube is attached to what?

A

the base of the skull

34
Q

What does the inferior end of the pharynx join?

A

the esophagus

35
Q

Where is the pharynx deficient?

A
  • the anterior wall where it communicates with the nasal cavity at the posterior chonae
  • where it communicates with the oral cavity at the oropharyngeal isthmus
  • lowest deficiency is where it communicates with the larynx inlet
36
Q

What is the epithelial lining made of that lines the mucus membrane of the pharynx?

A

it is either respiratory or stratified squamous where it comes in contact with the contents of the digestive tract

37
Q

Where does the pharyngobasilar fascia lie?

A

outside the mucus membrane of the pharynx, separating the membrane from the posterior muscular wall

38
Q

What is the buccopharyngeal fascia and what does it allow for?

A

lines the back of the pharynx, allows for pharyngeal expansion and mobility

39
Q

How many pharyngeal constrictor muscles are there and what are they?

A

3; superior, middle, inferior constrictors

40
Q

The 3 constrictors muscles do what posteriorly?

A

overlap

41
Q

What happens as the pharyngeal constrictors extend anterolaterally?

A

they diverge from each other

42
Q

What is the pharyngeal raphe?

A

a vertical fibrous band into which each half of all 3 constrictors attach to posteriorly

43
Q

What are the attachments of superior constrictor

A

superiorly, various aspects of the base of skull and then it sweeps posteriorly to attach to the pharyngeal tubercle of the occipital bone

44
Q

At the top of the superior constrictor muscle, what is present that is not present in the middle and inferior?

A

A large lateral deficiency

45
Q

What closes the lateral deficiency of the superior constrictor?

A

pharyngobasilar fascia

46
Q

What perforates the pharyngobasilar fascia?

A

auditory tube

47
Q

Where does the middle constrictor arise from?

A

arises anteriorly from the stylohyoid ligament and hyoid bone

48
Q

How does the middle constrictor extend posteriorly?

A

fans posteriorly to enclose the lower aspects of the superior constrictor and attach to the pharyngeal raphe

49
Q

the lower fibers of the middle constrictor do what?

A

arch posteriorly to the level of the larynx

50
Q

What two things pass through the gap between the superior and middle constrictors?

A

stylopharyngeus muscle and glossopharyngeal nerve

51
Q

Where does the inferior constrictor arise from?

A

from the oblique line of the thyroid cartilage and the cricoid cartilage and sweeps posteriorly to overlap the middle constrictor

52
Q

What are all 3 constrictor muscles innervated by?

A

pharyngeal plexus (CN X)

53
Q

What innervates the stylopharyngeus muscle?

A

glosspharyngeal n.

54
Q

Where does the stlyophargeus muscle arise from?

A

it descends from the medial aspect of the styloid process and passes between the superior and middle constrictor attaching to the posterior border of the thyroid cartilage

55
Q

Where does the salpingopharyngeus muscle arise from?

A

arises from the expanded medial end of the cartilage of the auditory tube and descends on the inside of the superior constrictor to attach to the thyroid cartilage

56
Q

What innervates the salpingopharyngeus muscle?

A

the pharyngeal plexus from CN X

57
Q

Motor innervation of the pharnyx is primarily from what?

A

pharyngeal plexus (CN X)
