Across
  1. 1. Openings located posterolateral to the foramen ovale; provides passageway for middle meningeal artery (2)
  2. 7. Articulate with the mandibular fossa of the temporal bones (2)
  3. 10. Located lateral to the crista galli; form a portion of the roof of the nasal cavity and the floor of the anterior cranial fossa (2)
  4. 11. Facial bones that articulates with all other facial bones except the mandible. Forms upper jaw and parts of the hard palate, orbits, and nasal cavity
  5. 13. Slits in the orbits providing passage of cranial nerves that control eye movements including III, IV, VI, and the opthalmic division of V (3)
  6. 14. Bone that forms the forehead, superior part of the orbit, and the floor of the anterior cranial fossa
  7. 15. Tiny holes in the cribriform plates that allow the passage of filaments of a cranial nerve I (2)
  8. 18. Bone that is commonly called the cheekbones; each forms part of the lateral orbit
  9. 19. A bridgelike projection that articulates with the zygomatic bone to form an arch(2)
  10. 20. Rounded projections lateral to the foramen magnum that articulate with the atlas vertebra(2)
  11. 21. Bone that articulates with all other cranial bones
  12. 22. Portion on the ramus for muscle attachment (2)
  13. 25. Bone that contributes to the anterior cranial fossa; forms part of the nasal septum and the nasal cavity (2)
  14. 29. Suture where the left and right parietal bones meet superiorly in the midline of the cranium
  15. 32. Inferior projection of the ethmoid bone that forms the superior portion of the nasal septum (2)
  16. 37. Suture running in the frontal plane, where the parietal bones meet the frontal bone anteriorly
  17. 39. Located inferior to the zygomatic process on the temporal bone;forms a joint with the mandibular condyle(2)
  18. 40. Tiny opening between the mastoid and the styloid process through which cranial nerve VII leaves the cranium(2)
  19. 41. Form part of the floor of the anterior cranial fossa and part of the orbit (2)
  20. 44. Lower jawbone
  21. 45. Superior and middle are on the ethmoid bone and improve airflow through the nasal cavity (2)
  22. 46. Separate the condylar process and the coronoid process (2)
  23. 48. Superior projection of the ethmoid bone that attaches to the dura mater, helping secure the brain to the skull (2)
  24. 49. Openings located in the medial part of the greater wing; the maxillary branch of cranial nerve V passes through (2)
  25. 51. Located on the medial surface of each ramus; passageway for the nerve involved in tooth sensation (2)
  26. 52. Paired openings on the body of the mandible; transmits blood vessels to the lower lip and the skin of the chin (2)
  27. 53. Small rectangular bones forming the bridge of the nose
Down
  1. 2. Canal leading to external ear and eardrum (3)
  2. 3. Posterior points where the ramus meets the body (2)
  3. 4. Bone that forms the superior and lateral aspects of the skull
  4. 5. Needlelike projection that serves as an attachment point for ligaments and muscles of the neck.(2)
  5. 6. Almost completely closed by cartilage in a living person but forms a jagged opening in dried skulls(2)
  6. 8. Located on the superior surphase of the sphenoid body, hold the pituitary gland (2)
  7. 9. Bone that forms the inferolateral aspects of the skull
  8. 12. Opening medial and superior to the occipital condyle through which cranial nerve XII passes(2)
  9. 16. Openings located posterolateral to the foramen rotundum; the mandibular division of cranial nerve V passes through (2)
  10. 17. Openings in the base of the lesser wings: cranial nerve II passes through to serve the eye (2)
  11. 23. Project inferiorly from the greater wings; attachment site for chewing muscles (2)
  12. 24. Bone that forms the posterior aspect and most of the base of the skull
  13. 26. Located posterior to the external acoustic meatus; serves as an attachment point for neck muscles(2)
  14. 27. Bone that forms the part of the lateral walls of the nasal cavities; improves airflow (3)
  15. 28. Opening above each orbit allowing blood vessels and nerves to pass (2)
  16. 30. Thin, blade-shaped bone that forms the inferior nasal septum
  17. 31. Inferior margin of the maxilla; contains sockets in which the teeth lie (2)
  18. 33. Bone that forms part of the medial orbit in between the maxilla and ethmoid bones
  19. 34. Bone that forms posterior portion of the hard palate
  20. 35. Large opening in the base of the bone, which allows the spinal cord to join with the brain stem(2)
