1
Oropharynx-
Visible in back of mouth
2
Pharyngopharynx-
Below(inferior to) oropharynx
3
Pharynx functions
Respiratory-helps breathe
Digestive-mastication
Middle ear pressure
4
Muscles of soft palate forms roof of..
The oropharynx and laterally with the tongue
5
Soft palate muscle functions-
Speaking and swallowing
6
Soft palate innervation-
Pharyngeal plexus,
CN- 9,10,11
7
Palatoglossus muscle forms:
Palatoglossal arch
2 arches
*when someone says "ahh"
8
Palatopharyngeus muscle action-
Palate moves posterioinferior and posterior pharyngeal wall anterosuperior.
*closes off the nasopharynx to the oral pharynx
9
What closes the pharynx?
The palate
10
Levetor veli palatini muscle location
Superior to soft palate
11
Lavator veli palatini action-
Elevates the soft palate to contact posterior pharyngeal wall
*so we don't have stuff go up nose
12
Levetor veli palatini innervation-
Pharyngeal plexus
13
Tensor veli palatini is active during:
All palatine movements
*busy muscle
14
Tensor veli palatini actions:
Opens Eustachian tube, tenses and depresses soft palate
15
Tensor veli palatini innervation
Tensor veli palatini nerve-branch of V3 mandibular division.
16
Uvula
O:
I:
O: posterior margin of soft palate
I: counterpart of opposite side
17
Uvula action
Shorten and broaden the uvula
18
Uvula innervation
Pharyngeal plexus
19
Nasopharynx-
Superior to soft palate
20
Constrictor muscles insertions, actions, and innervations:
Superior-
Middle-
Inferior-
Insertion-median pharyngeal raphe
Action- elevate pharynx, larynx
Innervation- pharyngeal plexus
21
Stylopharyngeus
O:
I:
O: styloid process
I: lateral and posterior pharyngeal walls
22
Stylopharyngeus action
Widens and elevates pharynx
23
Stylopharyngeus innervation
CN 9
24
Hyoid muscles assist in...
Swallowing and mastication
25
The suprahyoid (above hyoid) group contains what 4 muscles
Digastric,
Mylohyoid,
Geniohyoid,
Stylohyoid
*all same action: elevate hyoid and depress mandible
26
Digastric muscle action-
#1 of suprahyoids
Elevate hyoid/tarynx, depress mand
*assist in swallowing
27
Digastric innervation
Anterior belly-
Posterior belly-
Ant- V3
Post- 7
28
Mylohyoid forms:
#2 of suprahyoids
The floor of the mouth
29
Mylohyoid
O:
I:
O: mylohyoid ridge
I: body of hyoid
