Davis who allowed me the opportunity to write this textbook in the manner in which I teach my students. I am particularly grate- ful to Quincy McDonald, Acquisition Editor, and to Jennifer Pine, Senior Developmental Editor, who encouraged and guided me through writing and organization of this textbook. No anatomical textbook would be complete without vivid illustrations. I would like to acknowledge David F. Baker, Supervisor of Medical Illustrations, of the Academic Technology Services of The University of Texas Health Science Center at San Antonio, for the wonderful illustrations in the book. I would like to thank two of my colleagues, Drs. Earlanda L. Williams and Damon C. Herbert for their support and suggestions while writing this book. I would like to also thank Dr. Archie Jones of the Department of Periodontology who helped me with the photographing of the structures of the oral cavity. Finally, I would like to thank my family and students: the students for their encour- agement and suggestions, and my wife and family for their patience and support throughout the completion of this textbook. ix
