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






2. 2 branches of nervous system






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






4. 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






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






6. Front area of the body






7. Blood vessel that carries blood away from heart - has muscles on inside of walls






8. Artery to max molars






9. Some Say Marry Money - But My Brother Says - Bad Business - Marry Money






10. Single bone - only movable bone of the face - many landmarks - largest and strongest facial bone - articulates with temporal bone to form TMJ

12. Feeds all area of face. connects to external carotid artery






13. XI nerve - synergist to Vagus nerve - Motor






14. Generally immovable articulation in Which bones are joined by fibrous tissue






15. VII nerve - muscles of facial expression - tear glands - salivary glands - sensory and motor






16. Under tongue






17. XII nerve - primarily tongue movement - motor






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






19. 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






20. 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)






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






22. Prominen bridgelike bony structure






23. Structure at the median plane






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






25. Type of blood vessel that carries blood away from the heart






26. Lingual Nerve






27. Opening or canal in the bone






28. Only vein that carries oxygenated blood






29. 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






30. Structure closest to the palate






31. Biggest artery in body






32. Back of an area of the body






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

35. Back of an area of the body






36. Site of a junction or union between two or more bones






37. 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






38. IV cranial nerve - motor - movement of eyeball






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






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






41. 3rd and largest division of trigeminal nerve - sensory and motor to mandible






42. 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






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






44. Network of veins that comes together (paired)






45. Number of bones in the skull






46. Erythrocytes






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






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






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