students structure for organizing this wealth of information.
Below are the ways in which we’ve revised the Ninth Edition
to make this book the one where learning happens most effec-
tively, followed by a detailed list of specific chapter-by-chapter
content changes.
An expanded art program.
Te drive for this revision began as
a simple list. We sat down together and created a chapter-by-
chapter list of the key concepts in A&P where students struggle
the most. Tis list became the basis for our art revision plans for
both the Eighth and Ninth editions. We first boiled it down to
some of the toughest topics to get our list of Focus figures. Tese
Focus figures are illustrations that use a “big picture” layout and
dramatic art to walk the student through difficult physiological
processes in a step-by-step way. Tese have been wildly popular
with both instructors and students. In response to repeated re-
quests for more, we are pleased to present 12 new Focus figures.
We hope you’ll be as pleased with the results of the added Focus
figures in the Ninth Edition as you were in the Eighth.
All of the art in the Eighth Edition was carefully examined
and reviewed by both instructors and students. Many of their
suggested changes have been incorporated into this edition. As
always, we have updated many figures to reflect the latest sci-
entific findings and to improve their ability to teach important
concepts. Finally, many new photos—histology, cadaver, and
others—were painstakingly chosen for this edition to enhance
the learning process.
Flipping through the Ninth Edition, you can see that we
have built upon the dynamic, three-dimensional, and realistic
art style, utilizing dramatic views and perspectives and vibrant,
saturated colors.
Improved text presentation.
New text features initiated in the
Eighth Edition that focus students on key concepts have been
retained and expanded in the Ninth Edition. In the current
edition, student objectives still appear by topic throughout the
chapter and some new
Check Your Understanding
questions
have been added at the end of sections. Tese changes along
with a brand-new design make the book easier than ever to
study from and navigate. Our hallmark analogies and acces-
sible, friendly style while using simpler, more concise language
and shorter paragraphs make the information easier for stu-
dents to manage.
Factual updates and accuracy.
As authors we pride ourselves on
keeping our book as up-to-date and as accurate as possible in all
areas—a monumental task that requires painstaking selectivity.
Although information changes even as a textbook goes to press,
be assured that our intent and responsibility to update has been
carried out to the best of our ability. We have incorporated cur-
rent research in the field as much as possible; many of these up-
dates are included in the chapter-by-chapter changes. A more
complete list is available from your Pearson sales representative
and in the
Instructor Guide
to Text and Media.
Terminology changes.
For this edition we’ve substantially up-
dated the terminology to be in accordance with
Terminologia
Anatomica
and
Terminologia Histologica
. Professors can find a
complete list of terminology changes detailed in the
Instructor
Guide to Text and Media.
