what is vestibule
space between teeth and inner mucosal lining of lip and cheek
what is oral cavity proper
space contained in upper and lower dental arches
vestibule
anterior boundary
lateral boundary
- lips
- cheeks
THE ORAL CAVITY PROPER BOUNDARIES ant/ lat post sup inf
teeth
Oropharyngeal isthmus
hard palate
mylohyoid muscle
Roof of the mouth and floor of nasal cavity
Anterior 2/3
posterior 1/3
- hard palate- palatine process of maxilla and horizontal plates of palatine bone
- soft palate - mostly in oropharynx
All palatine muscles except Tensor Veli Palatine - motor supply from
cranial part of accessory nerve via vagus nerve
Tensor veli palatine is supplied by
mandibular branch of trigemenal nerve
what goes thru
incisive foramen
greater palatine foramen
lesser palatine foramen
- nasopalatine nerve and greater palatine vessels and nerve
- greater palatine vessels and nerve
- lesser palatine nerve and vessels

what is Alveolar mucosa
sheet of muscosa between gingiva and labial muscle
Alveolar mucosa bound
loosely to alveolar bone
the external carotid branches
