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.

29. With this procedure - no x-ray film is involved at all






30. Calcium 'bridges' between adjacent vertebrae

32. Is to the right - it produces the electrons






33. Distance from the grid to the x-ray tube (36-40 inches)






34. The greater the number of electrons released






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