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






14. Structures located toward the surface of the body






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






16. Depression and elevation of jaw - occurs between disc and condyle of lower synovial cavity






17. Paired bones - landmark- infraorbital foramen - has processes with 4 different bones






18. VI cranial nerve - motor - movement of eyeball






19. Artery to mandible






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






21. Occipital - frontal - parietal-paired - temporal- paired - sphenoid - ethmoid






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






23. Foreign material or thrombus traveling in the blood that can block the vessel






24. 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






25. Area where the bones are joined to each other






26. Paired - most posterior part of the hard palate - they fuse together to form hard palate - greater palatine foramen located @ posterior lateral region






27. Cervical muscles - muscles of facial expression - muscles of mastication - muscles of tongue - muscles of the pharynx - muscles of the hyoid - muscles of the soft palate






28. Trauma to a blood vessel






29. Largest gland. paired. located in front of ear - outside of skull - under skin and muscle. Stenson's Duct. Serous secretions- 25% of total volume. Responsible for mumps






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

33. Section of the body through any frontal plane






34. Anterior 2/3 of tongue






35. Part of lymphatic system that runs parallel to most veins in the body






36. 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






37. 3 TMJ Ligaments






38. Paired glands lcoated inside the medial angle of mandible - walnut sized - Wharton's Duct - Mixed salivary compostion- 60-65% - Empties behind mandibular anterior teeth






39. Tubercle or rounded elevation on a bony surface






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






41. Houses/forms sockets of teeth - bone on facial surface is thin - effected by perio dz - resorbs quickly after extraction - forms as deciduous teeth erupt






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






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






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






45. When atherosclerosis occurs in arteries leading to the heart






46. Artery to max premolars






47. Artery to tongue






48. Portion of mandible that connects to the TMJ






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






50. Cellular component pertaining to nervous system
