Some of the drawings have been borrowed or emphasis on their clinical relevance and this is a change that is long adapted from Professor Harold Ellis’s superb book Clinical Anatomy overdue. However, students still have examinations to pass and in this (9th edn) and we are most grateful to him for his permission to do this. book the authors, a surgeon and an anatomist, have tried to provide a We should also like to thank Dr Mike Benjamin of Cardiff University means of rapid revision without any frills. To this end, the book follows for the surface anatomy photographs. Finally, it is a pleasure to thank the standard format of the at a Glance series and is arranged in short, all the staff at Blackwell Science who have had a hand in the prepara- easily digested chapters, written largely in note form, with the appro- tion of this book, particularly Fiona Goodgame and Jonathan Rowley. priate illustrations on the facing page. Where necessary, clinical appli- cations are included in italics and there are a number of clinical Omar Faiz illustrations. We thus hope that this book will be helpful in revising and David Moffat consolidating the knowledge that has been gained from the dissecting room and from more detailed and explanatory textbooks.
