8. Control center - one of the major divisions of nervous system - composed of brain and spinal cord - surrounded by skull and spinal vertebrae for protection






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






10. Connects to aorta






11. Singe bone - bat-shaped - forms anterior base of skull - many foramen and processes - landmark- greater wing of sphenoid






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






13. Single bone - forms the forehead and the top of the eye - contains supraorbital notch - location of frontal sinuses






14. Artery to cheek






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






16. 4 bones with processes attaching to maxilla






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






18. 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






19. Tube through which sound waves are transmitted to the middlbe ear within the skull






20. Loss of muscle actions in muscles of facial expressions






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






22. Paired - irregular thin plates of bone that forms the medial wall of the orbit - lacrimal glands (tear ducts) present @ the margin of this bone






23. Network of blood vessels - usually veins






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

34. Smallest structural unit of living matter capable of functioning independently






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






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






37. Structure closest to lips






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






39. Only vein that carries oxygenated blood






40. Section of the body through any horizontal plane






41. Carries info away from brain/spinal cord to the body - (info from brain)






42. To join together; in the periodontium - a complex system of blood vessels supplies blood to the periodontal tissues

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






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






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