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. II cranial nerve - sensory - sight and visual impluses






2. Structure closest to the palate






3. Huge foramen in occipital bone through which the spinal cord passes






4. Back of an area of the body






5. Water saliva composition






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






7. Sinuses located in sphenoid bone - cannot be palpated in oral exam






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






9. Muscle auto-responses from body - ex: breathing - digestion - heartbeat - eyes






10. Resident microorganisms that usually do not cause infections






11. Smaller vein that drains the capillaries in the tissue area






12. Depression and elevation of jaw - occurs between disc and condyle of lower synovial cavity






13. Forms sockets of teeth






14. Sensory nerve that carries information from the periphery of the body to the brain or spinal cord






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






16. Triangular area where medial and lateral views of the mandible come together - Provides support for patients with lower partial






17. Largest of paranasal sinuses - paired - located within the maxilla - Significant to dentistry with max post exts-perforation - max sinus infections - implant placements/sinus lifts - and with air travel- with infection - descension is painful






18. Inner side of the wall of a hollow structure






19. VII nerve - muscles of facial expression - tear glands - salivary glands - sensory and motor






20. Chemical agen that is discharged to cause action of a muscle






21. Plane created by an imaginary line that divides the body into right and left halves






22. A joint on each side of the ehad that allows for movement of the mandible - speech - and mastication - Location: where condyle of mandible articulates with the zygomatic process of the temporal bone






23. V- trigeminal - VII- facial






24. Filters toxins and other foreign bodies out of body - typically green in diagrams - has valve system similar to veins






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. IV cranial nerve - motor - movement of eyeball






27. Paired bones - landmark- infraorbital foramen - has processes with 4 different bones






28. Part of lymphatic system that runs parallel to most veins in the body






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






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






31. Region of the head located inferior to the orbial region and lateral to the nasal region






32. Structures located toward the surface of the body






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






34. Towards the crown of a tooth






35. A virus - microorganism - or other substance that causes dz






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






37. Control center - one of the major divisions of nervous system - composed of brain and spinal cord - surrounded by skull and spinal vertebrae for protection






38. Number of cranial bones






39. Also known as malar bone - forms cheek bone - forms zygomatic arch with temporal bone - 4 process form arch - often seen in panoramic and PAX






40. Pair bones Landmarks- Infraorbital foramen Processes- alveolar - zygomatic - frontal - and palatine






41. Attaches several muscles to mandible






42. Single bone - forms the forehead and the top of the eye - contains supraorbital notch - location of frontal sinuses






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






44. 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






45. Foreign material or thrombus traveling in the blood that can block the vessel






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






47. Decreased saliva flow






48. Short canal leading to the tympanic cavity






49. 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






50. Hollow organ - dual action pump - thick muscular walls - right side pumps to lungs - left side pumps to body
