These well-known and popular manuals appear in their fifteenth edition in an entirely new format. The text has been redesigned to make it more accessible to the student, to highlight key terms, and to set the dissection guide apart from the main text. Illustrations have been revised, with many improvements and new additions. The text has been expanded to include more explanations and new material on embryology, organogenesis, congenital malformations of clinical significance, and new imaging and diagnostic techniques such as CT scanning.
