MODULE SOLVED ITEMS AND RESPONSE KEY
◉ Lingual foramen Answer: radiolucent dot located near the midline
and on the lingual aspect of the mandible surrounded by the genial
tubercles
◉ Nutrient canals Answer: radiolucent tubelike passageways
through bone that contain nerves and blood vessels and seen in the
mandibular anterior region
◉ Mental ridge Answer: radiopaque thick linear prominence of
cortical bone located on external surface of the anterior portion of
the mandible and extends from the premolar region to the midline
and is sloped
◉ Mental fossa Answer: radiolucent scooped-out depressed area of
bone located on the exterior surface of the anterior of the mandible
and located superiorly to the mental ridge
◉ Mental foramen Answer: radiolucent opening or hole in bone
located on the external surface of the mandible in the region of the
apices of the premolars
,◉ Mandibular canal Answer: radiolucent band with radiopaque
borded that is a passageway and extends from the mandibular
foramen to the mental foramen and houses the inferior alveolar
nerve and blood vessels
◉ External oblique ridge Answer: radiopaque linear prominence of
bone located on the external surface of the body of the mandible
◉ Mylohyoid ridge/internal oblique ridge Answer: radiopaque
linear prominence of bone located on the internal surface of the
mandible and extends from the third molar region downward and
forward to the second premolar area
◉ Submandibular fossa Answer: radiolucent scooped-out, depressed
area of bone located on the internal surface of the mandible inferior
to the mylohyoid ridge and home of the submandibular salivary
gland
◉ Coronoid process Answer: radiopaque marked prominence of
bone located on the anterior ramus of the mandible
◉ Incisive foramen Answer: radiolucent opening or hole in the bone
located at the midline of the anterior portion of the hard palate
, directly posterior to the maxillary central incisors adn site of exit of
the nasopalatine nerve
◉ Medial palatal suture Answer: radiolucent line between the
maxillary incisors that is an immoveable joint between the two
palatine processes of the maxilla and extends from the alveolar bone
between the maxillary incisors to the posterior hard palate
◉ Superior foramina of the incisive canal Answer: two radiolucent
openings or holes in the bone that is located on the floor of the nasal
cavity and the canals join to form the incisive canal
◉ Lateral/canine fossa Answer: radiolucent smooth depressed area
of the maxilla located just inferior and medial to the infraorbital
foramen between the maxillary canine and lateral incisors
◉ Nasal cavity Answer: radiolucent pear-shaped compartment of
bone located superior to the maxilla and divided into two
compartments by the nasal septum
◉ Nasal septum Answer: radiopaque partition that divides the nasal
cavity into right and left nasal fossae
