Fichas del conjunto (16)
- 1What are the main bony components of the hard palate?Palatine processes of the maxillae and the palatine bones
- 2What is the structure called that houses the upper teeth?Alveolar arch
- 3What are the three foramina called on the hard palate?Incisive fossa, greater and lesser palatine foramina
- 4Which nerve runs through the incisive fossa?Nasopalatine nerve
- 5What are the transverse folds called on the inferior surface of the hard palate?Palatine rugae
- 6What is the median longitudinal ridge called that forms on the hard palatePalatine raphe
- 7What structure overlies the incisive fossa on the hard palate?Incisive papilla
- 8What structure can be found hanging on the posterior free margin of the soft palate?Uvula
- 9What is the palatine aponeurosis an expansion of?Tensor veli palatini tendons
- 10Which structures form the majority of the posterior part of the soft palate?Palatine muscles
- 11What are the structures the arrows are pointing to?
- 12What 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 - 13What 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 - 14What 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 - 15What 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 - 16What 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
