1. Single bone - forms back of head - landmark- foramen magnum - (huge hole in this bone through which the spinal cord passes)






2. Artery to cheek






3. 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






4. Bundle of neurons






5. Paired sinuses located in frontal bone - separated by septum - drains into nasal cavity - irregularly shaped

7. Nerve supply to the periodontium






8. Structure closest to lips






9. Dislocation of joints






10. There are no ________ in the veins of the head and neck - which makes infection very easy to spread and to linger in an area






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






12. Muscle of facial expression - origin- encircles the mouth - insertion- angle of mouth - actions: closes lips - pursing lips - rolling lips inward - puckering






13. 3 TMJ Ligaments






14. Area that is farther away from the median plane of the body






15. Shaded area of lips that is darker than surrounding skin






16. Artery to tongue






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






18. Inside of the mouth






19. Both watery and ropey saliva composition combined






20. Network of veins that comes together (paired)






21. Section of the body through the median plane






22. Sinuses located in sphenoid bone - cannot be palpated in oral exam






23. Also known as malar bone - forms cheek bone - helps form zygomatic arch - paired






24. Prefix meaning too much






25. V cranial nerve - sensory and motor - supplies most oral features and facial muscles - teeth - tongue - palate






26. Sensory nerve that carries information from the periphery of the body to the brain or spinal cord






27. Paired - forms bridge of nose






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






29. Inner side of the wall of a hollow structure






30. Innervates to the maxilla by the second branch and the mandible by the third branch - have sensory - motor - and intermediate roots that attach directly to the brain - responsible for the sensory sensibility of most of the skin of the front part of t






31. Type of injection that anesthetizes a small area- one or two teeth and associated structures- when the local anesthetic agent is deposited near nerminal nerve endings






32. Front area of the body






33. 2 valves of the heart

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






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






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






41. Protect - support - basis for movement - consideration in spread of dental infections






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






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






44. Paired bones - forms upper back side of skull






45. Section of the body through any frontal plane






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






47. Causes muscles to contract - stimulates glands - allows for sensations to be perceived






48. Outer side of the wall of a hollow structure






49. 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






50. Plane created by an imaginary line that divides the body @ any level into superior and inferior portions
