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
where does the palatine tonsil drain in to
the jugulo-digastric node
what happens to the palatine tonsil with age
it regresses
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

The skeletal muscles of the soft palate are all supplied by the CNs X/CN XI except for which muscle
tensor veli palatini which is supplied by mandibular division of the trigeminal nerve (CN V3).
which muscle of the soft palate is supplied by the trigeminal nerve
tensor veli palatini
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.

what is the function of the Levator veli palatini
elevation of the soft palate
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 function of the tensor veli palatini
tenses the soft palate
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.

clinically testing the movement/angulation of the uvula tests which cranial nerve
CN X (vagus nerve)
if there is unilateral nerve pathology the uvula will be pulled in which direction
the uvula willpull away from the non-functioning side.
- Stops food from entering the nose during swallowing
- Directs air in to the nose or the mouth during speech, sneezing, coughing and vomiting
- Helps to close off the entrance into the oropharynx during the gag reflex
these are features of what?
the trapdoor feature of the soft palate
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
