Anatomy of Orofacial structures 8th Edition
Where does the oral cavity begin and end? - (ANSWER)Begins and the lips and cheeks and
ends at the oral pharynx
What to systems do the oral cavity introduce? - (ANSWER)Beginning of the digestive system
At the posterior forms a common pathway with the respiratory system
Where do the tonsillar pillars lie? - (ANSWER)Between the anterior and posterior tonsillar
pillars
The oral cavity is divided into two parts: - (ANSWER)vestibule and oral cavity proper
Vestibule - (ANSWER)Space between the teeth and the inner mucosal lining of the lips and
cheeks
Where does an edentulous person's vestibule end? - (ANSWER)At the alveolar ridge
Oral Cavity Proper - (ANSWER)Area surrounded/contained by the teeth back to the area of the
palatine tonsils
Includes floor of the mouth and hard and soft palate
Vermillion zone - (ANSWER)
Vermillion Border - (ANSWER)area where the pink-red lip tissue meets the facial skin
lip line
Ala of the nose - (ANSWER)The wing of the nose or outer edge of the nostril
Nares - (ANSWER)nostrils
, 2
Labial commissure - (ANSWER)corners of the mouth
Philitrum - (ANSWER)vertical groove on the middle of the upper lip.
Cupids bow
Zygomaticoalveolar crest - (ANSWER)ridge of bone at the upper posterior vestibular space;
beginning of the anterior part of the zygomatic arch (cheekbone)
Mucobuccal/mucolabial fold - (ANSWER)Point at which the mucosa of the lips and cheeks
turns to go towards the gingival tissue
alveolar mucosa - (ANSWER)Mucosa lying against the alveolar bone that is loosely attached
and and moveable
What color is alveolar mucosa and why? - (ANSWER)Reddish because of the presence of
blood vessels underneath the thin mucosa
mucogingival junction - (ANSWER)Distinct line of color change in the tissue where the
alveolar membrane meets with attached gingivae
Labial Frenum (Frenulum) - (ANSWER)fold of connective tissue at the midline in upper and
lower lips
Diastema - (ANSWER)An open space between the two adjacent teeth.
What can cause a diastema? - (ANSWER)Large labial frenulum
To correct it must be surgically removed and if this procedure does not close it all the way mild
ortho treatment may be required.
Done between ages of 6-12
