Test your basic knowledge |

Dental Hygiene Boards Anatomy

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






2. Towards the crown of a tooth






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






4. 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






5. Normal flora creating an infectious process because the body's defenses are compromised






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






7. Transition zone betweek skin and vermillion zone






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






9. Inner side of the wall of a hollow structure






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






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






12. Causes muscles to contract - stimulates glands - allows for sensations to be perceived






13. 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






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






15. 2 accessory muscles of mastication






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






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






18. Point on upper lip where the philtrum terminates






19. Plane created by an imaginary line that divides the body @ any level into superior and inferior portions






20. Nerve supply to the periodontium






21. X nerve - vocal cords - heart - respiration - digestion - autonomic nervous system - sensory and motor






22. 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






23. Large amounts of blood that escape into the surroudning tissue without clotting - when a blood vessel is seriously injured






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






25. Largest gland. paired. located in front of ear - outside of skull - under skin and muscle. Stenson's Duct. Serous secretions- 25% of total volume. Responsible for mumps






26. Number of facial bones






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






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






29. XII nerve - primarily tongue movement - motor






30. Anterior 2/3 of tongue






31. Shifting of the lower jaw to one side






32. Structure at the median plane






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






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






35. Spread of cancer from primary location - once cancer enters lymphatic system - it can enter the blood stream and spread






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






37. Smallest structural unit of living matter capable of functioning independently






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






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






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






41. End of the muscle that is attatched to the more movable structure






42. Layers of soft tissue overlying the bones of the brain case






43. Number of cranial bones






44. 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






45. Connects to aorta






46. Paired bones - most posterior part of the hard palate - 2 bones fuse together @ the midline to form the hard palate - greater palatine foramen located @ posterior lateral region






47. Artery to max premolars






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






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






50. Area where the bones are joined to each other
