study
Midline
Imaginary line that divides the body
into right and left halves
Mesial
Surface closest to the midline
Distal
Surface farthest away from midline
Lateral
To the side of something
Posterior
Towards the back
Lingual
Towards the tongue
Anterior
Toward the front
Maxillae
Upper Arch
Vermilion Zone
transitional zone of reddish tissue joining skin of face with lips.
Mandible
Lower Arch
Philtrum
indentation at midline of upper lip
Vestibule
space between lips or cheeks and teeth
Oral Cavity
Area extending from lips and
posteriorly to palatine tonsils.
Oral Cavity Proper
area from teeth or alveolar ridges back to tonsils
labial vestibule
Anterior vestibule
buccal vestibule
Lateral vestibule
Labial Frenum
Fold of tissue at midline in both upper and lower lips
Retromolar pad
elevated tissue behind last mandibular molar.
Maxillary tuberosity
elevation on the posterior part of the maxillary body
Lingual Frenum
part of the Oral Cavity
Proper not the Vestibule
Ankyloglossia
“tongue-tied”; caused by frenum that is attached too close to the tip of the tongue
Diastema
Max. lip frenum may cause Maxillary centrals to separate
Incisive papilla
bulge of tissue at midline just posterior to central incisors
Hard palate
anterior portion of roof of mouth
Rugae
ridges of tissue found on hard palate
Soft palate
posterior portion of roof of mouth; forms uvula
Exostoses
small bony growths in vestibule area
Torus palatinus
excess boney growth in midline of hard palate on maxilla
Torus mandibularis
excess boney growth on lingual
surface of mandible.
Fauces
space between left and right tonsils
Lingual Frenum
fold of tissue extending from near tip of tongue to floor of
mouth
palatine tonsils
Normally just called tonsils; found at the side of the throat opposite the back of the tongue.
tonsillar pillars
The vertical folds of tissue that lie in front of and behind the palatine tonsils in the lateral throat wall.
oral pharynx
The area behind the oral cavity that runs from the palatine tonsils to the back wall of the throat.
labia
lips
Bucca
cheeks
Superior
Above
Inferior
Under
Fordyce granules
Misplaced sebaceous glands in the lips, cheek, or retromolar pad area.
zygomaticoalveolar crest
Heavy ridge of maxilla and zygomatic bone that forms a heavy supporting ridge running up from the alveolar process of the maxillary premolar–molar region.
coronoid process
Bony projection at the upper anterior ramus of the mandible; point of attachment for the temporal muscle
cortical plate
Dense bone on the buccal and lingual surfaces of the alveolar bone
posterior pillar
palatopharyngeal arch or fold.
anterior pillar
palatoglossal arch or fold.
sublingual caruncle
Small elevation of soft tissue at the base of the lingual frenum that is the opening for the submandibular duct.
sublingual fold
Fold of tissue extending backward on either side of the floor of the mouth; duct of the submandibular gland lies below it.
