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.

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. Paired bones - irregular thin plates of bone that forms the medial wall of the orbit (eye) - lacrimal (tear duct) glands are present @ the margin of these bones






2. Structures located inward - away from the body surface






3. 2 branches of peripheral nervous system

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






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






7. Joint located inferior to the zygomatic arch and just anterior to the ear - where upper skull forms a joint with the lower jaw






8. Blood vessel that carries blood to heart - operates by valves






9. Largest endocrine glandthyroxine - should be part of extraoral exam- palpate - goiter- inflammed neck - responsible for metabolic rate and temp- control






10. 2 branches of autonomic nervous system






11. Area that faces away from the head and toward the feet of the body






12. Number of bones in the skull






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






14. Area closer to the median plane of the body






15. General term for any prominence on a bony surface






16. Bundle of neurons






17. Ropey saliva composition






18. Any plane of the body created by an imaginary plane parallel with the median plane






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






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






21. Network of veins that comes together (paired)






22. Artery to #6-11






23. TMJ Located lateral side of each joint forms a reinforcement of the capsule of the TMJ - Prevents excessive retraction of the mandible






24. 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






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






26. Posterior 1/3 of tongue






27. Corners of mouth






28. Area that is closer to the median plane of the body or structure






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






30. VI cranial nerve - motor - movement of eyeball






31. Bacteria traveling within the vascular system






32. Structures located toward the surface of the body






33. 3 TMJ Ligaments






34. Important part of blood composition for clotting






35. Tiny blood vessel that branches off small artery to supple blood to tissue






36. Bringing backward of the lower jaw






37. Secreted to specific locations by ducts; salivary and lacrimal glands






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






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






40. A band of fibrous tissue that connects bones






41. IV cranial nerve - motor - movement of eyeball






42. 2nd division of trigeminal nerve - sensory to maxilla and surrounding tissues - suicide nerve- can effect women 40+ years old on right side and causes excruciating pain (also called Tie Douleureaux or Trigeminal Neuralgia)






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






44. 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






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






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






47. Zygomatic process of temporal bone - temporal process of zygomatic bone - maxillary process of zygomatic bone - zygomatic process of maxillary bone






48. Point on upper lip where the philtrum terminates






49. Portion of mandible that connects to the TMJ






50. Structures on the opposite side of the body
