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.

16. Movement accomplished by a muscle when the muscle fibers contract






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






18. Back of an area of the body






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






20. Structures closest to the tongue






21. Divides space between bones






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






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






24. Structures closest to the facial surface






25. 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






26. Inner side of the wall of a hollow structure






27. Anterior Superior Alveolar Nerve






28. Gasserion ganglion present - 3 divisions feeding eye - maxilla - and mandible






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

37. Muscles used for walking and tirggered by thought






38. Structures located toward the surface of the body






39. 2 accessory muscles of mastication






40. Provides ventilation to head - lightens skull - drainage - acts as sound resonators - provides mucous for nasal cavity - can be involved with allergies or infection as in primary sinusitis or in tooth infection as in secondary sinusitis






41. Network of blood vessels - usually veins






42. Posterior superior alveolar nerve






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

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






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






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






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






49. Paired bones - forms upper back side of skull






50. Mylohyoid nerve
