body of the mandible; radiopaque
alveolar ridge - CORRECT ANSWER-bony ridge that contains
the alveoli (tooth sockets); radiopaque
Mental process or ridge - CORRECT ANSWER-Linear
prominence of bone on the external surface of the anterior
mandible that extends from the premolar region; radiopaque
Nasal septum (vomer bone) - CORRECT ANSWER-Bone
structure that divides the left/right of the nasal cavity;
radiopaque
Nasal fossa (cavity) - CORRECT ANSWER-Two large
depressions of bone located above maxilla and divided by the
nasal septum; radiolucent
anterior nasal spine - CORRECT ANSWER-a triangular
projection from the floor of the nasal fossa, located at junction
of fossa and septum; radiopaque
Lateral fossa/canine fossa - CORRECT ANSWER-slightly
concave area in bone located below and between the maxillary
lateral incisors and maxillary canine; radiolucent
Mental fossa - CORRECT ANSWER-Depressed area of bone
on the external surface of the mandible; radiolucent
Hamulus/Humular process - CORRECT ANSWER-Small, hook
shaped portion of bone extending from sphenoid bone down
and located behind maxillary tuberosity region; radiopaque
Median palatal suture - CORRECT ANSWER-Line of fusion
between the palatine processes of the right and left maxilla;
radiolucent; between roots of maxillary incisors
,Incisive foramen - CORRECT ANSWER-Pear shaped opening
in bone located at midline of anterior hard palate behind central
incisors; nasopalatine nerve and vessels exit the maxilla from
the foramen; radiolucent
Mylohyoid ridge - CORRECT ANSWER-Linear prominence of
bone on the internal aspect of the mandible; mylohyoid muscle
attaches to ridge which extends from lower border of
mandibular symphysis; raidopaque
Submandibular fossa - CORRECT ANSWER-Depression in the
bone on the lingual side of the mandible in which the
submandibular salivary glands are located; large radiolucent
area below roots of mandibular molars
Lingual foramen - CORRECT ANSWER-Small opening located
in the midline of internal aspect of mandible through which a
branch of the incisive artery travels; radiolucent dot
Genial tubercles - CORRECT ANSWER-Small donut shaped
ring of tiny spines of bone that surround the lingual foramen
and are located near the midline on the internal aspect of the
mandible; radiopaque
Enamel - CORRECT ANSWER-calcified layer that covers
crown of tooth; radiopaque
Dentin - CORRECT ANSWER-Mineralized tissue; makes up
main body of tooth; extends entire body of the tooth to protect
pulp; radiopaque
dentinoenamel junction - CORRECT ANSWER-Line of
demarcation where enamel and dentin meet; radiopaque
, Cementoenamel junction - CORRECT ANSWER-Area where
the cementum of root meets enamel of crown of tooth; not
usually distinguishable
Alveolar crest - CORRECT ANSWER-Most coronal portion of
the alveolar bone; where the two cortical bones join between
each tooth; linear radiopaque outline of the alveolar ridge can
be seen on radiographs
Pulp - CORRECT ANSWER-Interior of tooth which contains
nerves, blood vessels, and lymphatic tissue; radiolucent
Periodontal ligament - CORRECT ANSWER-Connective tissue
that supports and suspends the teeth in their position within the
dental arch; the fibers attach to the lamina dura, lining bone of
the alveolus and the cementum of the root; radiolucent
Alveolar bone - CORRECT ANSWER-Bone that surrounds and
supports the tooth in its position in the jaw; radiopaque
Cementum - CORRECT ANSWER-Calcified tissue covering the
root of the tooth; periodontal ligament attaches to the
cementum to anchor tooth within the socket; not distinguishable
on radiographs
Lamina dura - CORRECT ANSWER-Bony wall of the tooth
socket that surrounds the root; radiopaque
Apical foramen - CORRECT ANSWER-Opening in the apex of
the tooth that provides for access of nerves, blood vessels, and
lymphatics; not distinguishable on radiographs
Apex (apices) - CORRECT ANSWER-General term for tip of
the root of the tooth; usually seen as a continuation of
radiopaque outline of the root
