Articulatory System: Pharyngeal Muscles Flashcards
Pharyngeal muscles
Inferior constrictor
Middle constrictor
Superior constrictor
Stylogpharyngeus
Inferior constrictor Attachments
Thyroid cartilage
Pharyngeal raphe
Located in the walls of the laryngopharynx
Inferior constrictor Functions
Facilitates opening of esophagus
Narrows vocal tract, which alters resonance characteristics (Higher frequency)
Middle constrictor Attachments
Hyoid bone
Pharyngeal raphe
Located in the walls of the oropharynx
Middle constrictor Function
Narrows vocal tract, altering the resonance characteristics
Superior constrictor Attachments
Medial pterygoid
Pterygomandibular ligament
Pharyngeal raphe
Hamulus
Located in the walls of the nasopharynx
Superior constrictor Function
Narrows vocal tract, alters resonance characteristics
Contributes to velopharyngeal mechanism by raising the velum
Stylopharyngeus Attachments
Styloid process
Lateral walls of pharyngeal cavity
Thyroid cartilage
Stylopharyngeus Functions
Raises larynx
Widens vocal tract, alters resonance characteristic (Lower frequency)
Important for swallowing large mass
