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. Paired bones - landmarks- mastoid process - styloid process - zygomatic process - external auditory meatus






2. Inferior alveolar nerve






3. Located in the ethmoid bone - cannot be palpated in oral exam






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






5. Area that is farther away from the median plane of the body






6. Connects to common carotid arter






7. Runs from styloid process of temporal bone to the angle of the mandible - taut when mandible is protruded






8. Loss of muscle actions in muscles of facial expressions






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






10. The narrowing and blockage of the arteries by a buildup of plaque






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






12. End of the muscle that is attatched to the more movable structure






13. When atherosclerosis occurs in arteries leading to the heart






14. Shaded area of lips that is darker than surrounding skin






15. Front area of the body






16. Some Say Marry Money - But My Brother Says - Bad Business - Marry Money






17. Area closer to the median plane of the body






18. Allows jaw to move forward and backward - occurs between disk and articular eminence in the upper synovial cavity






19. Not part of TMJ - but rather on the medial side of the mandible - Attaches @ spine of sphenoid bone to the lingual of the mandibular foramen - becomes taut when mandible is protruded






20. Shuts down communication of nerves and neurons by blocking the chemicals from entering at the synapses






21. Number of cranial bones






22. Smaller blood vessel that branches off an arteriole to supply blood directly to tissue






23. Single bone - also known as nasal septum - forms midline of nose - not important to oral cavity - forms inferior portion of nasal septum






24. Mono- - lymph- - leukocytes; varying types






25. Paired glands lcoated inside the medial angle of mandible - walnut sized - Wharton's Duct - Mixed salivary compostion- 60-65% - Empties behind mandibular anterior teeth






26. Type of body tissue that shortens under neural control - causing soft tissue and bony structures to move






27. Nerve supply to the periodontium






28. Communication of a blood vessel with another blood vessel by a connecting channel






29. Network of veins that comes together (paired)






30. End of the muscle that is attached to the least movable structure






31. 3 TMJ Ligaments






32. Artery to mandible






33. Single bone - forms back of head - landmark- foramen magnum - (huge hole in this bone through which the spinal cord passes)






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






35. 4 muscles of mastication






36. Forms part of cheekbone with zygomatic arch - often seen in panoramic and periapical films






37. General term for any prominence on a bony surface






38. Both watery and ropey saliva composition combined






39. Connects anterior superior alveolar artery and middle superior alveolar arter to the maxillary artery

43. Prefix meaning too much






44. Carries info away from brain/spinal cord to the body - (info from brain)






45. Pointed end of a conical structure






46. Abnormal sensation from an area such as burning or prickling
