where do the elevator muscles of the pharynx (5) insert?
pharyngeal constrictor muscles and posterolateral border of thyroid cartilage
Palatopharyngeus muscle origin
soft palate
Levator Veli Palatini muscle origin
base of skull and travels under medial pterygoid plates bilaterally
Salpingophayngeus muscle origin
cartilaginous part of pharyngotympanic tub
Stylopharyngeus muscle origin
Styloid Process
muscularis uvulae muscle origin
posterior nasal spine
Functions:
Palatopharyngeus muscle
Levator Veli Palatini muscle
Salpingophayngeus muscle
Stylopharyngeus muscle
Muscularis uvulae muscle
Palatopharyngeus muscle: elevates pharynx, closes larynx when swallowing
Levator Veli Palatini muscle: elevates soft palate during swallowing
Salpingophayngeus muscle: elevates pharynx, equalize pressure in middle ear
Stylopharyngeus muscle: swallowing
Muscularis uvulae muscle: elevate uvula
Palatopharyngeus muscle function
Elevates pharynx
Closes larynx when swallowing
Levator Veli Palatini muscle function
Elevates soft palate during swallowing
Salpingopharyngeus muscle function
Elevates pharynx
Equalize pressure in middle ear
Stylopharyngeus muscle function
helps with swallowing
Muscularis Uvulae muscle function
elevate uvula
