Radiology 3

Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Mostly seen in mandibular nerve/blood supply vertical radiolucent lines






2. Used to decrease voltage from the incoming 110- or 220-line voltage to the 3 to 5 volts used by the filament circuit.






3. Surrounded by genial tubercle - hole in bone near mandibular midline - radiolucent






4. Gray






5. Bump of bone - muscle attachment; lingual aspect of mandible - 'ring shaped' radiopacitiy below mandibular incisors.






6. Hollow space - cavity that appears radiolucent






7. Located above maxillary premolar/molar teeth - border is made up of cortical bone; sinus cavity is radiolucent compartment






8. Continues from ramus; radiopaque band






9. Occurs very little; most photons pass through cell with little or no damage






10. Thin - curved areas of bone - radiopacities within nasal cavity and septum






11. 8 inch and 16 inch; longer are preferred due to less divergence of beam - open ended and lead lined.






12. 68 Degrees F






13. Area of body exposed total body produced more adverse effects






14. A form of secondary radiation - the result of x-rays that has been deflected from its path by an interaction with matter.






15. Two small openings (radiolucent) found on floor of nasal cavity->common exit is incisive foramen






16. Coulombs per kilogram






17. An x-ray photon that has its path altered by matter.






18. Within maxillary sinus; acts as a division - radiopaque lines sometimes not visible






19. More damage can occur in younger or rapidly dividing cells






20. Superior to internal oblique ridge; anterior border of ramus ends in external oblique ridge; radiopaque band






21. Suggest that no matter how small the amount of radiation received - some biologic damage occurs.






22. Posterior to mandibular third molar






23. Surrounds root - cortical bone - radiopaque






24. 'Cheekbone'; cortical bone; radiopaque band extending from zygomatic process.






25. Can control the current passing from the cathode to the anode.






26. Bump or nodule that appears radiopaque






27. Time between exposure to ionizing radiation and the appearance of observable clinical signs.






28. The measurement of electrical force that causes electrons to move from a negative pole to a positive one. Measured in volts (V) or kilovolts (kV)






29. Used to increase incoming voltage to 65 -000 to 100 -000 volts used by the high-voltage circuit.






30. Intersection of maxillary sinus and nasal cavity - radiopaque - cortical bone; above maxillary canine.






31. Cortical bone - radiopaque band above maxillary incisors






32. Marked prominence that appears radiopaque.






33. Bony wall that divides 2 spaces - radiopaque






34. Internal ridge of mandible muscle attachment - continuous with internal oblique ridge; radiopaque line






35. 'Arranged like a lattice'->soft - spongy bone located between 2 layers of cortical bone; spaces are trabeculae that are filled with bone marrow.






36. Primary beam passes through glass window - insulating oil - tubehead seal. 0.5 to 1.0 mm of aluminum






37. Small lymphocyte - bone marrow - reproductive cells - immature bone






38. U-shaped portion extending from ramus to ramus






39. 'hooklike' - posterior to maxillary tuberosity; extension of medial pterygoid plate of sphenoid bone; radiopaque






40. 16-20 square feet (at least 4x4) - Light tight - Safelight must be at least 4 feet from the working area






41. Tube that travels length of mandible - radiolucent; has cortical walls - houses inferior alveolar nerve






42. Can increase or decrease the number of electrons passing through the cathode filament






43. Encases/supports teeth






44. Located at the midline of anterior portion of hard palate behind maxillary central incisors; round radiolucency between roots of centrals






45. Removes unexposed silver halide crystals and creates white/clear areas on film; black metallic silver remains on film.






46. Darkness or blackness on film. If kVp is increased film will be darker. If decreased - film will be lighter






47. Opening/hole in bone that allows the passage of blood vessels/nerves and appears radiolucent






48. Bony prominence posterior to maxillary third molar; radiopaque






49. Rounded prominence that appears radiopaque






50. Occurs frequently due to the high concentration of water in cells.
