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.

2. I cranial nerve - sensory - sense of smell






3. Several arteries branch directly off the aorta to feed the _____________






4. Important part of blood composition for clotting






5. Paired - irregular thin plates of bone that forms the medial wall of the orbit - lacrimal glands (tear ducts) present @ the margin of this bone






6. Also known as trigeminal ganglion - Where the 3 division of trigeminal nerve meet






7. Section of the body through any frontal plane






8. 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






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






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






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






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






13. Mineralized structures of the body that protect internal soft tissues and serve as the biomechanical basis for movement






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






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






16. 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






17. Generally immovable articulation in Which bones are joined by fibrous tissue






18. Structures closest to the inner cheek






19. 'flight or flight' responses






20. Network of blood vessels - usually veins






21. Infection of the maxillary sinus






22. Tubercle or rounded elevation on a bony surface






23. Posterior 1/3 of tongue






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






25. Main portion of the anterior border of ramus






26. Shifting of the lower jaw to one side






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






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






29. 4 muscles of mastication






30. 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






31. 1st and smallest division of trigeminal nerve - carries sensory information to brain - sensory for eyeball - cornea - and forehead






32. Section of the body through any horizontal plane






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






34. Inferior alveolar nerve






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






36. Mucole that appear in floor of mouth of major salivary glands






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






38. Site of a junction or union between two or more bones






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






40. V cranial nerve - sensory and motor - supplies most oral features and facial muscles - teeth - tongue - palate






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






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






43. Forms sockets of teeth






44. Loss of funtion of the 6th cranial nerve

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






46. Network of veins that comes together (paired)






47. Substance which consists of cholesterol (mainly) - calcium - clotting proteins - and other substances that can be found lining arteries






48. Section of the body through the median plane






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






50. Innervates to the maxilla by the second branch and the mandible by the third branch - have sensory - motor - and intermediate roots that attach directly to the brain - responsible for the sensory sensibility of most of the skin of the front part of t
