1. The bone that surrounds the roots of the teeth. It forms the bony sockets that support and protect the roots of the teeth






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






3. Results from incomplete fusion of the maxillary bones at palatine process - open area that can involve from no teeth to involving teeth - palate - lip - and nasal - can involve pedodontist - oral surgeon - and pediatrician some appliances may be need






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






5. Mylohyoid nerve






6. 2 accessory muscles of mastication






7. Artery to #6-11






8. Structures closest to the facial surface






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






10. XII nerve - primarily tongue movement - motor






11. XI nerve - synergist to Vagus nerve - Motor






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






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






14. Single bone - midline bone int he cranium - part of nose - lies behind the frontal bone - between the eyes - part of floor of cranial base






15. 2 places where bones grow at






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






17. Fuses with frontal bone facially






18. Inferior alveolar nerve






19. Begins process of breaking food down into simple sugars in saliva






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






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






22. 3rd and largest division of trigeminal nerve - sensory and motor to mandible






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






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






25. 'rest or digest' responses






26. 4 bones with processes attaching to maxilla






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






28. 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






29. Paired bones - forms upper back side of skull






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






31. Like a projection; an irregularly shaped extension named for where it is going






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






33. Erythrocytes






34. Single bone - only movable bone of face - many landmarks present - largest and strongest bone of face - articulates with temporal bone to form TMJ






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






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






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






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






39. Type of injection that anesthetizes a larger area than local infiltration because the local anesthetic agen is deposited near large nerve trunks






40. VIII nerve - hearing and balance - also known as auditory or vestibular cochlear - sensory and motor






41. Depression on one side of a lymph node where lymph flows out by way of an efferent lymphatic vessel






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






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






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






45. Artery to max molars






46. 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






47. Type of blood vessel that travels to the heart - carrying blood






48. Stone formed in glands - cause by minerals in saliva - causes facial swelling with recurrence with little pain - pt placed on antibiotic and sugar-free lemon drops to increase salivary flow - Oral surgeon can remove stone or part of gland if necessar






49. Ropey saliva composition






50. Lowering of the lower jaw
