5. Allows us to move - usually works in groups - 2 kinds- involuntary and voluntary






6. Structures located inward - away from the body surface






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






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






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






10. Paired glands located in the anterior floor of mouth under the tongue - smallest gland with many ducts - mixed salivay composition - but predominantly mucous- 10% volume






11. Divides space between bones






12. 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






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






14. Area that faces toward the head of the body - away from the feet






15. The loss of feeling or sensation resulting from the use of certain drugs or gases that seruve as inhibitory neurotransmitters






16. Joint located inferior to the zygomatic arch and just anterior to the ear - where upper skull forms a joint with the lower jaw






17. Zygomatic process of temporal bone - temporal process of zygomatic bone - maxillary process of zygomatic bone - zygomatic process of maxillary bone






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






19. Accumulation of neuron cell bodies outside the central nervous system






20. Bundle of neurons






21. Connects to common carotid arter






22. Characteristics that appear on a specific bone






23. Smaller blood vessel that branches off an arteriole to supply blood directly to tissue






24. Posterior superior alveolar nerve






25. Fuses with frontal bone facially






26. Important part of blood composition for clotting






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






28. Mono- - lymph- - leukocytes; varying types






29. Blockage of minor salivary gland - occurs mainly in lip - about the size of a dime - must be removed






30. Number of facial bones






31. Carries infor from the periphery of the body to brain or spinal cord






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






33. Bacteria traveling within the vascular system






34. Largest endocrine glandthyroxine - should be part of extraoral exam- palpate - goiter- inflammed neck - responsible for metabolic rate and temp- control






35. Capable of causing disease only when the host's resistance is lowered






36. Erythrocytes






37. Cavity within the bone






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






39. Paired bones - within the bony part of the nose - lateral portion of the nasal septum






40. Buccal Nerve






41. Outer side of the wall of a hollow structure






42. II cranial nerve - sensory - sight and visual impluses






43. 4 muscles of mastication






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






45. Single bone - midline bone of cranium - part of nose - lies behind the frontal bone - between the eyes






46. Structures on the opposite side of the body






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






48. Rising of the lower jaw






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






50. Allows jaw to move forward and backward - occurs between disk and articular eminence in the upper synovial cavity
