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. Region of the head that is lateral to the infraorbital region - overlies zygomatic arch (cheek bone)






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






3. Short canal leading to the tympanic cavity






4. Infection of the maxillary sinus






5. Tubercle or rounded elevation on a bony surface






6. Tiny blood vessel that branches off small artery to supple blood to tissue






7. Joint located inferior to the zygomatic arch and just anterior to the ear - where upper skull forms a joint with the lower jaw






8. Capable of causing disease only when the host's resistance is lowered






9. Corners of mouth






10. Single bone - bat-shaped - forms anterior base of the skull - has many foramens and processes - landmark- greater wing of sphenoid






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






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






13. Only vein that carries oxygenated blood






14. Front area of the body






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






16. Stone formed in glands - cause by minerals in saliva - causes facial swelling with recurrence with little pain - pt placed on antibiotic and sugar-free lemon drops to increase salivary flow - Oral surgeon can remove stone or part of gland if necessar






17. Allows us to move - usually works in groups - 2 kinds- involuntary and voluntary






18. Horizontal portion of mandible






19. 2 branches of peripheral nervous system






20. Divides space between bones






21. There are no ________ in the veins of the head and neck - which makes infection very easy to spread and to linger in an area






22. Area that faces toward the head of the body - away from the feet

24. Network of blood vessels - usually veins






25. Single bone - forms the forehead and top of the eye - has supraorbital notch






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






27. Structure closest to lips






28. Middle superior alveolar nerve






29. Structures located inward - away from the body surface






30. Bundle of neurons






31. Anterior 2/3 of tongue






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






33. Muscle - origin- sphenoid bone - insertion- angle of mandible - medial surface - action- elevates mandible - forms sling with masseter; synergist with masseter






34. Single bone - forms back of head - landmark- foramen magnum






35. Number of bones in the skull






36. Type of injection that anesthetizes a small area- one or two teeth and associated structures- when the local anesthetic agent is deposited near nerminal nerve endings






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






38. Muscle - origin- several different places on sphenoid - insertion- condyle - near TMJ - action- protrudes and lateral deviation of mandible - fibers run horizontally






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






40. Bacteria traveling within the vascular system






41. Under tongue






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






43. 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






44. Aiming area for palatal injections






45. III cranial nerve - motor - movement of eyeball and dilation of pupils






46. Position in which the body is erect - with arms @ the sides - plams and toes directed forward - and eyes looking forward






47. Nerve supply to the periodontium






48. Muscle of facial expression - origin- encircles the mouth - insertion- angle of mouth - actions: closes lips - pursing lips - rolling lips inward - puckering






49. Anterior Superior Alveolar Nerve






50. Structure at the median plane
