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






22. Structures closest to the inner cheek






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

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






26. Site for large muscles of the neck to attach






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






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






29. Muscle - origin- sphenoid bone - insertion- angle of mandible - medial surface - action- elevates mandible - forms sling with masseter; synergist with masseter






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






31. Also known as malar bone - forms cheek bone - forms zygomatic arch with temporal bone - 4 process form arch - often seen in panoramic and PAX






32. Artery to max molars






33. Located in the ethmoid bone - cannot be palpated in oral exam






34. 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






35. Connects to common carotid arter

46. Drains everything from head and neck area to the heart






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