Anatomy and innervation of palate Flashcards
The attachment of the mucosa on to the bone is called the
mucoperiosteum.
injecting LA in the hard palate would be painful why?
because of the compact bone
lack of space
and the lack of mucosa compared to other areas of the oral cavity
what is skeletal muscle of the oral cavity covered by
mucosa
name this suture
median palatine suture
where would the palatine process of the maxilla be found
where is the incisive canal located
where are the horizontal plates of the palatine bones located
where is the maillary tubersoity located
name this suture
incisive suture
name this suture
transverse palatine suture
locate and name the foramina and the nerve that passes through it
greater and lesser palatine foramen
branches of CN V2
where is the pterygoid hamulus located
medial pterygoid plate
The lateral and medial pterygoid plates of the sphenoid bone sit posterior to what?
maxillary tuberosity
how is the midline ridge (palatine raphe) formed on the palate
fusion of the left and right palatal shelves
complication of the fusion results in cleft palate
what is the name of this landmark, which is present fromn birth
incisive papilla
where would you expect to find keratinised stratified squamous epithelium
hard palate
non - keratinised in soft palate
which nerve passes through the incisive fossa
nasopalatine nerve (V2)
where would stimulus from the greater/lesser palatine nerves synpase to
pterygopalatine ganglion
which fossa does the pterygopalatine ganglion sit inferiorly to
pterygopalatine fossa
which nerve innervates the hard palate
greater palatine nerve
which nerve innervates the soft palate
lesser palatine nerve
a branch of the nasoplatine nerve passes through the incisive foramen to supply what? (incisive branch)
supplies palatal gingivae of anterior teeth & mucosa of the anterior palate
Lymphatic drainage of the anterior palate drains to where
the submandibular glands
Lymphatic drainage of the hard and soft palate drains into what
retropharyngeal nodes, located in the retropharyngeal space
where does the attachment of the levator veli palatini arise from
arises from the petrous temporal bone and the eustachian tube
where does Levator veli palatini insert into
the palatine aponeurosis.
where does the attachment of the Tensor veli palatini originate
Originates from the medial pterygoid plate of the sphenoid
where does the tensor vele palatini insert into
in to the palatine aponeurosis
what is the name of the muscle that wraps itself arounf the pterygoid hamulus
tensor veli palatini
which soft palate muscle arises from the posterior nasal spine and the palatine aponeurosis and inserts in tothe mucous membrane
muculus uvulae
where does the attachment of the palatoglossus originate from and insert into
Originates from the palatine aponeurosis, and travels anteriorly, laterally and inferiorly to insert into the side of the tongue.
what is the function of the palatoglossus
pulls the soft palate towards the tongue
where does the palatopharyngeus arise and insert into
Arises from the palatine aponeurosis and the hard palate and inserts into the upper border of the thyroid cartilage.
where is the salpingopharyngeus (auditorytubve located)
where is the tensor celi palatini located
where is the levator veli palatini located
where is the palatopharyngeus located
whereis the superior constrictor of pharynx located
wher eis the middle constrictor of the pharynx located
where is the palatoglosses located
where is the tensor veli palatini located
where is the levator veli palatini located
where is the salpingopharyngeus located
where is the palatopharyngeus located
where is the superior constrictor located
