2. Connects anterior superior alveolar artery and middle superior alveolar arter to the maxillary artery






3. XII nerve - primarily tongue movement - motor

15. Pointed end of a conical structure






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






17. Structures located inward - away from the body surface






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






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






20. Paired bones - forms bridge of the nose






21. Water saliva composition






22. Disorder involving one or both temporomandibular joints






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






24. 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






25. Chemical agen that is discharged to cause action of a muscle






26. Single bone - also known as nasal septum - forms midline of nose - not important to oral cavity - forms inferior portion of nasal septum






27. Region of the head where the external ear is a prominent feature






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






29. Network of veins that comes together (paired)






30. Bundle of neurons






31. Nerve supply to the periodontium






32. Type of lymphatic vessel in which lymph flows into the lymph node






33. Back of an area of the body






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






35. Runs from styloid process of temporal bone to the angle of the mandible - taut when mandible is protruded






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






37. Prefix meaning too much






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






39. 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






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






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






42. Artery to tongue






43. Lymph node that drains lymph from a primary node






44. Type of body tissue that shortens under neural control - causing soft tissue and bony structures to move






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






46. 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






47. Dislocation of joints






48. 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






49. 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






50. IV cranial nerve - motor - movement of eyeball
