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.

17. Large amounts of blood that escape into the surroudning tissue without clotting - when a blood vessel is seriously injured






18. Muscle of facial expression - helps mastication by keeping food on the chewing surface - cheek muscle






19. Single bone - only movable bone of face - many landmarks present - largest and strongest bone of face - articulates with temporal bone to form TMJ

23. Connects to common carotid arter






24. Blood vessel that carries blood away from heart - has muscles on inside of walls






25. Articular fossa - articular eminence - condyle - articular disc - synovial fluid

32. Type of blood vessel that carries blood away from the heart






33. Structures closest to the facial surface






34. Singe bone - bat-shaped - forms anterior base of skull - many foramen and processes - landmark- greater wing of sphenoid






35. Erythrocytes






36. Watery basis of blood composition






37. Area that is farther away from the median plane of the body or structure






38. 2nd division of trigeminal nerve - sensory to maxilla and surrounding tissues - suicide nerve- can effect women 40+ years old on right side and causes excruciating pain (also called Tie Douleureaux or Trigeminal Neuralgia)






39. Artery to cheek






40. TMJ Located lateral side of each joint forms a reinforcement of the capsule of the TMJ - Prevents excessive retraction of the mandible






41. Paired bones - irregular thin plates of bone that forms the medial wall of the orbit (eye) - lacrimal (tear duct) glands are present @ the margin of these bones






42. 2 branches of autonomic nervous system






43. The loss of feeling or sensation resulting from the use of certain drugs or gases that seruve as inhibitory neurotransmitters






44. Vomer - lacrimal bones- paired - inferior nasal conchae- paired - zygomatic bones- paired - maxillary bones- paired - mandible
