Test your basic knowledge |

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.

13. What is the term for when the animal's bowel engulfs a piece of bowel distal to it - causing blockage






14. What gives off 4 times the amount of light photons than does the calcium tungstate (it gives off green light)






15. We ideally take a radiograph of the abdomen at the peak of inspiration






16. The shorter the wavelength of the x-ray - the more powerful the x-ray is






17. Slowly growing dividing cells are the most sensitive to the effects of ionizing radiaton






18. Outer layer of disk ( dries out and cracks and causes disk to herniate)






19. What is the name for the cartilage flap in the shoulder joint that has broken free and is floating around in the joint fluid






20. Screen speed is.....to the exposure required to cause it to flouresce






21. A lightproof encasement designed to hold x-ray film and intensifying screens in close contact






22. These crystals will turn white/clear when processing film






23. When this is exposed to x-rays - it will absorb photons (quanta) and give off photons of visible light which the film is sensitive to (give off blue light)






24. This number in santes' rule refers to the distance the x-ray tube is from the x-ray film






25. Bone - lymphatic cells - epitheilial - and hemopoietic cells are also what kind of cell?






26. If there's far or muscle in the way of an x-ray - those parts would be






27. Weakness






28. The electrical current sent through the filament to cause this electron release is called






29. The layer of the film where the action occurs






30. What specific part of the eye is cloudy with a cataract






31. Pigments tend to decrease the lateral spread of light so there is increased detail






32. If there's metal in the way of an x-ray - than no x-rays will get through and that part would be






33. In the dark room - the safe light (red light) needs to be at least how far away from the loading bench






34. Faster screens/less detail; slower screens/more detail






35. What type of film gives more detailed radiographs but more exposure to everyone involved? (commonly used as dental film - or for extremities)

47. Grid helps reduce the amount of......






48. What must have little or no 'afterglow'






49. This pertains to the size of the electron cloud and thus directly to the number of x-ray produced






50. Calcium 'bridges' between adjacent vertebrae
