Insight Sidebars

Each chapter has from two to six special topic sidebars called Insights, listed by title and page number on the opening page of each chapter. These fall into three categories: 101 clinical applications, 13 on medical history, and 9 on evolutionary medicine. For a quick survey of their subject matter, see the lists under these three phrases in the index.

Clinical Applications

It is our primary task in A&P to teach the basic biology of the human body, not pathology. Yet students want to know the relevance of this biology—how it relates to their career aims. Furthermore, disease often gives us our most revealing window on the importance of normal structure and function. What could better serve than cystic fibrosis, for example, to drive home the importance of membrane ion pumps? What better than brittle bone disease to teach the importance of collagen in the osseous tissue? The great majority of Insight sidebars therefore deal with the clinical relevance of the basic biology. Clinical content has also been enhanced by the addition of a table for each organ system that describes common pathologies and page-references others.

Medical History

I found long ago that students especially enjoyed lectures in which I remarked on the personal dramas that enliven the history of medicine. Thus, I incorporated that approach into my writing as well, emulating something that is standard fare in introductory biology textbooks but has been largely absent from A&P textbooks. Reviews have shown that students elsewhere, like my own, especially like these stories. I have composed 13 historical and biographical vignettes to have an especially poignant or inspiring quality, give students a more humanistic perspective on the field they've chosen to study, and, I hope, to cultivate an appropriately thoughtful attitude toward the discipline. Historical remarks are also scattered through the general text.

Profiles of Marie Curie (p. 58), Rosalind Franklin (p. 132), and Charles Drew (p. 694) tell of the struggles and unkind ironies of their scientific careers. Some of my favorite historical sidebars are the accounts of William Beaumont's digestive experiments on "the man with a hole in his stomach" (p. 977); Crawford Long's pioneering surgical use of ether, until then known mainly as a party drug (p. 628); the radical alteration of Phineas Gage's personality by his brain injury (p. 538); and the testy relationship between the men who shared a Nobel Prize for the discovery of insulin, Frederick Banting and J. J. R. MacLeod (p. 671).

Evolutionary Medicine

The human body can never be fully appreciated without a sense of how and why it came to be as it is. Medical literature since the mid-1990s has shown increasing interest in "evolutionary medicine," but most A&P textbooks continue to disregard it. Chapter 1 briefly introduces the con

Later chapters have nine Evolutionary Medicine insights and shorter evolutionary remarks in the main body of text. Students will find novel and intriguing ways of looking at such topics as mitochondria (p. 124), hair (p. 204), skeletal anatomy (p. 286), body odors (p. 595), the taste for sweets (p. 990), the nephron loop (p. 897), lactose intolerance (p. 970), menopause (p. 1060), and senescence (p. 1114).
