Define the anatomical term: alveolar bone
the bone of the maxilla and mandible that supports and encases the teeth
Define the anatomical term: alveolar crest
the most coronal portion of the alveolar bone found between teeth; composed of dense cortical bone
Define the anatomical term: alveolar process
the portion of the mandible that encases and supports teeth
Define the anatomical term: anterior nasal spine
a sharp projection of the maxilla located at the anteroinferior portion of the nasal cavity
Define the anatomical term: body of the mandible
the horizontal U-shaped portion of the mandible that extends from ramus to ramus
Define the anatomical term: canal
a tubelike passageway through bone that houses nerves and blood vessels
Define the anatomical term: cancellous bone
the soft, spongy bone located between two layers of dense cortical bone; appears like a latticelike structure
Define the anatomical term: coronoid process
a marked prominence of bone located on the anterior ramus of the mandible
Define the anatomical term: cortical bone/compact bone
the dense outer layer of bone
Define the anatomical term: dentin
the tooth layer found between the enamel and surrounding the pulp cavity
Define the anatomical term: dentino-enamel junction (DEJ)
the junction between the dentin and enamel of a tooth
Define the anatomical term: enamel
the outermost layer of of the crown of a tooth; the densest structure found in the human body
Define the anatomical term: external oblique ridge
a linear prominence of bone located on the external surface of the body of the mandible
Define the anatomical term: floor of the nasal cavity
a bony plate formed by the palatal processes of the maxilla and the horizontal processes of the palatine bones
Define the anatomical term: foramen
an opening or hole in bone that permits the passage of nerves and blood vessels
Define the anatomical term: fossa
a broad, shallow, scooped-out or depressed area of bone
Define the anatomical term: genial tubercles
tiny bumps of bone located on the anterior-lingual aspect of the mandible; serve as attachment sites for the genioglossus and geniohyoid muscles
Define the anatomical term: hamulus
a small, hooklike projection of bone that extends from the medial pterygoid plate of the sphenoid bone
Define the anatomical term: incisive foramen
an opening or hole in bone located at the midline of the anterior portion of the hard palate, directly posterior to the maxillary central incisors
Define the anatomical term: inferior nasal conchae
wafer-thin , curved plates of bone that extend from the lateral walls of the nasal cavity
Define the anatomical term: internal oblique ridge
a linear prominence of bone located on the internal surface of the mandible that extends downward and forward from the ramus
Define the anatomical term: inverted Y
a radiographic landmark that represents the intersection of the maxillary sinus and the nasal cavity
Define the anatomical term: lamina dura
the wall of the tooth socket that surrounds the root of a tooth
Define the anatomical term: lateral fossa
a smooth, depressed area of the maxilla located just inferior and medial to the infraorbital foramen between the maxillary canine and lateral incisors
