13. Structures closest to the facial surface






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






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

23. Dislocation of joints






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






25. 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






26. Area closer to the median plane of the body






27. Structures located toward the surface of the body






28. Posterior 1/3 of tongue






29. Attaches several muscles to mandible
