|
| What are the attachments, innervation and action of the tensor veli palatini muscle? | Attachements = cartilage of pharyngotympanic tube, medial pterygoid plate and spine of sphenoid bone to palatine aponeurosis Innervation = nerve to medial pterygoid (CNV) Action = Opens pharyngotympanic tube during swallowing and yawning & tenses soft palate to allow other muscles to function more effectively |
| What are the attachments, innervation and action of the levator veli palatini muscle? | Attachments = cartilage of pharyngotympanic tube and petrous part of temporal bone to palatine aponeurosis Innervation - pharyngeal branch (CNX) Action = elevates soft palate during yawning and swallowing, closing pharyngeal isthmus |
| What are the attachments, innervation and action of the palatoglossus muscle? | Attachments = palatine aponeurosis to side of tongue Innervation = pharyngeal branch (CNX) Action = depresses soft palate and elevates posterior part of tongue assisting in closing the oropharyngeal isthmus |
| What are the attachments, innervation and action of the palatopharyngeus muscle? | Attachments = palatine aponeurosis and hard palate Innervation = pharyngeal branch (CNX) Action = depresses soft palate assisting in closing the oropharyngeal isthmus |
| What are the attachments, innervation and action of the musculus uvulae muscle? | Attachment = palatine aponeurosis and posterior nasal spine Innervation = pharyngeal branch (CNX) Action = elevates and retracts uvula this assists in closing the pharyngeal isthmus |
