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.

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






4. Network of blood vessels - usually veins






5. Mylohyoid nerve






6. Blockage of minor salivary gland - occurs mainly in lip - about the size of a dime - must be removed






7. 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






8. Region of the head where the external ear is a prominent feature






9. Structures closest to the facial surface






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






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






12. Connects to common carotid arter






13. Single bone - only movable bone of the face - many landmarks - largest and strongest facial bone - articulates with temporal bone to form TMJ






14. Forms hard palate - fuses in teh middle at suture line - If fusion doesn't occur - cleft palate forms






15. Nerve supply to the periodontium






16. Also known as cribriform plate - thin layer of bone that lines the socket to surround the root of the tooth






17. Cavity within the bone






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






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






20. Rising of the lower jaw






21. Lymph node that drains lymph from a primary node






22. Front area of the body






23. All cranial nerves are ________






24. Also called a meniscus - attached to condyle on medial and lateral poles - shape conforms with shape of adjacent articulating bones - completely divides TMJ into 2 compartments - can be wrinking - torn - hardened - or detached on one end






25. When atherosclerosis occurs in arteries leading to the heart






26. Artery to #6-11






27. Paired bones - within the bony part of the nose - lateral portion of the nasal septum






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






29. Structures closest to the tongue






30. Forms sockets of teeth






31. Houses/forms sockets of teeth - bone on facial surface is thin - effected by perio dz - resorbs quickly after extraction - forms as deciduous teeth erupt






32. Muscle in the floor of the mouth - attaches to mylohyoid ridge






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






34. Protect - support - basis for movement - consideration in spread of dental infections






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






36. V- trigeminal - VII- facial






37. Muscles used for walking and tirggered by thought






38. Only artery that carries deoxygenated blood - carries it to the lungs






39. Cervical muscles - muscles of facial expression - muscles of mastication - muscles of tongue - muscles of the pharynx - muscles of the hyoid - muscles of the soft palate






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






41. Top posterior of tongue






42. Structures located inward - away from the body surface






43. Swelling of lymph nodes :abnormal enlargement' - can be helped with antibiotic
