what are the two parts of the palate?
hard palate - immobile and bony

the superior and inferior palatal surfaces have different mucosal linings - what are they?
superior (nasal cavity) - respiratory epithelium
inferior (oral cavity) - oral mucosa populated by secretory salivary glands
what is the bony structure of the hard palate formed from?
- palatine processes of maxilla
- horizontal plates of palatine bones
what are the 3 main foramina in the hard palate?
- incisive canal
- greater palatine foramen
- lesser palatine foramina
what does the incisive canal transmit?
nasopalatine nerve
what does the greater palatine foramen transmit?
greater palatine nerve and vessels
what does the lesser palatine foramina transmit?
lesser palatine nerve
what central process hangs from the midline of the posterior border of the soft palate?
uvula
the soft palate forms the roof of what?
the fauces - connects the oral cavity and the pharynx
what binds the palate to the tongue and pharynx?
- anteriorly - palatoglossal arch
- posteriorly - palatopharyngeal arches
what lies between the palatoglossal arches and the palatopharyngeal arches?
palatine tonsils
where do the palatine tonsils lie?
within the tonsillar fossae of oropharynx
what 5 muscles give action to the soft palate?
- tensor veli palatini
- levator veli palatini
- palatoglossus
- palatopharyngeus
- musculus uvulae
what is the function of the tensor veli palatini?
tenses the soft palate
