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. 4 bones with processes attaching to maxilla






2. Carries messages to the brain and carries messages from brain part of central nervous system






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






4. Drains everything from head and neck area to the heart






5. Outer side of the wall of a hollow structure






6. Fuses with frontal bone facially






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






8. Pointed end of a conical structure






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






10. Plane created by an imaginary line that divides the body at any level into anterior and posterior portions






11. Area closer to the median plane of the body






12. Oblique ridge - mental foramen - mandibular canal - alveolar process - mylohyoid grooves - mandibular foramen - lingula retromolar pad






13. Anterior Superior Alveolar Nerve






14. Structure at the median plane






15. Region of the head that is lateral to the infraorbital region - overlies zygomatic arch (cheek bone)






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






17. 1st and smallest division of trigeminal nerve - carries sensory information to brain - sensory for eyeball - cornea - and forehead






18. 2 places where bones grow at






19. Point on upper lip where the philtrum terminates






20. Not part of TMJ - but rather on the medial side of the mandible - Attaches @ spine of sphenoid bone to the lingual of the mandibular foramen - becomes taut when mandible is protruded






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






22. Structures closest to the tongue






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






24. Under tongue






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






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






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






28. Connects to aorta






29. Lymph node that drains lymph from a primary node






30. 2 valves of the heart






31. Paired - most posterior part of the hard palate - they fuse together to form hard palate - greater palatine foramen located @ posterior lateral region






32. Loss of muscle actions in muscles of facial expressions






33. Artery to max molars






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






35. 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






36. Allows jaw to move forward and backward - occurs between disk and articular eminence in the upper synovial cavity






37. Muscles used for walking and tirggered by thought






38. Network of veins that comes together (paired)






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






40. Only vein that carries oxygenated blood






41. 3rd and largest division of trigeminal nerve - sensory and motor to mandible






42. Area where the bones are joined to each other






43. Watery basis of blood composition






44. Artery to cheek






45. VI cranial nerve - motor - movement of eyeball






46. Structures on the same side of the body






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






48. Bringing forward of the lower jaw






49. Artery to max premolars






50. A band of fibrous tissue that connects bones
