This remains the only comparative study of the five principal species of small mammals used in biomedical research. In this unique two-volume set, the authors illustrate in superb detail the anatomy of each species, permitting comparisons between species and highlighting morphological differences of clinical significance. An essential reference for anyone performing surgical or post-mortem procedures. This volume discusses the rat, mouse and golden hamster. Includes artwork to illustrate the position and orientation of structures in situ in the living animal, as they will be encountered in carrying out a physical examination or surgical procedure. Illustrations of cross-sectional anatomy aid interpretation of diagnostic imaging such as ultrasonography.
