T2Q4 Palate, Muscles Flashcards
most muscles act on the soft palate swallowing mediate palatopharyngeus Overview: 5 muscles innervation: 4 by Vagus, 1 by V3 Origin: 2 from hard palate Insertion: 2 palantine aponeurosis swallowing: palatopharyngeus
tensor veli palatini: action!
tenses palate
levator palatini: action!
elevates palate
palatopharyngeus: action! (2)
Swallowing
- depresses soft palate
- elevates wall of pharynx
palatoglossus: action! (2)
- depresses soft palate
2. elevates tongue
muscularis uvuale: action
shortens/ elevates uvula
tensor veli palatini: innervation
V3
levator veli palatini: innervation
Vagus CN X
palatoglossus: innervation
Vagus CN X
palatopharyngeus: innervation
Vagus CN X
muscularis uvulae: innervation
Vagus CN X
musculus uvulae: origin & insertion
hard palate-> uvula
tenses/ elevates uvula
palatopharyngeus:origin & insertion
hard palate->pharyngeal wall, thyroid cartilage
SWALLOWING
depress soft palate, elevate pharynx
palatoglossus: origin & insertion
palatine aponeurosis-> glossus (sides)
elevates glossus, depresses soft palate
levator veli palatini: origin & insertion
eustachian tube-> palatine aponeurosis
elevates soft palate
tensor veli palatini: origin & insertion
schapoid (sphenoid bone)-> palatine aponeurosis
tenses soft palate
