Chapter 18Ten (Plus One) Terrific Online ResourcesIn This Chapter䊳 Scanning online reference books䊳 Exploring databases and virtual toursNo matter how much you study or how many Latin and Greek roots you memorize,it’s inevitable that some aspects of anatomy and physiology will leave you dazed andconfused. But if you study within reach of an Internet connection, you don’t have to staythat way for long. Simply surf over to one of the 11 sites covered in this chapter and startentering search terms. As with anything Internet-related, however, you have to be cautiousabout the accuracy of what you find. Just keep our mantra in mind: “When in doubt, trustthe textbook.”Answers and More Answerswww.answers.comAdmittedly, this free Web site doesn’t focus on anatomy and physiology, but you won’t reallycare about that technicality after you’ve dived into it a few times. The site offers about 4 mil-lion “answers” based more on keyword searches than on any actual questions. Material isdrawn from scores of brand-name content publishers as well as Answers.com’s own editorialteam. Can’t quite figure out where an “anteroinferior” something is supposed to be? Forgotwhere Peyer’s patches are hiding? Not entirely sure what a gallbladder does? Answers.com’sfriendly little “Tell me about . . .” box at the top of the home page takes you straight to a Webpage that aggregates what various sources say on your chosen topic.Into the Lion’s Denwww.lionden.com/ap.htmWe told you to trust the textbook, didn’t we? That means that you can probably trustthe textbook’s author, too. This delightful site is maintained by a Missouri communitycollege professor who also happens to be coauthor of an anatomy and physiology textbook.Dr. Kevin T. Patton has been teaching the subject for more than two decades and has devel-oped a refreshingly gentle sense of humor along the way. His Web site is packed with studytips, downloadable PowerPoint slides, and guided tours of various anatomical systems.
The Venerable Gray’swww.bartleby.com/107When we refer to “Gray’s Anatomy,” we’re not talking about the popular TV series of asimilar name. We’re talking about the venerable reference book that dates back to 1858and is now online for quick and easy access. Included in the “virtual” Gray’s Anatomy ofthe Human Body are more than 1,200 color illustrations and a subject index with 13,000entries. If your textbook is missing critical illustrations, don’t worry; a quick keywordsearch on this Web site can reveal a number of relevant graphics for you to study.Alluring Anatomistswww.anatomy.orgThe American Association of Anatomists believes that anatomy is “truly the backboneof biomedical science.” With that in mind, the organization has put together an Ask theExpert feature that lets anyone — students and educators alike — query the group’sworking professionals. To access this feature, click the Education and Teaching Toolslink on the organization’s home page; then select Ask the Expert. (To view the answerto a particular posted question, click on the question.)From the Education and Teaching Tools page, you also can find a list of popular linksto various subspecialties, including cell biology, genetics, imaging, molecular develop-ment, endocrinology, forensics, and physical anthropology.Getting Body Smartwww.getbodysmart.comThis Web site is the brainchild and passion of an anatomy and physiology instructor,Scott Sheffield, who says in his site’s mission statement that he’s attempting to distilltwo decades of teaching into a single, fully animated and interactive e-book about thehuman body. In addition to “flash” windows that drill down into various systems,GetBodySmart offers free tutorials and quizzes to explain complex physiologicalinteractions. Sheffield readily acknowledges that his work will last “many years,”so perhaps the best is yet to come.Pop Quiz Centralmsjensen.education.umn.edu/webanatomyMurray Jensen, an associate professor at the University of Minnesota, conductsresearch on the use of technology in science education. His Web site is both an out-growth of his research and a source of ideas for it. As of this writing, the site consistsmostly of dozens of quizzes of varying lengths and difficulty. Treat this site like yourown personal flash card system and you’ll be head and shoulders above your fellowstudents.288Part VI: The Part of Tens
MEDTropolis – Virtual Bodywww.medtropolis.com/VBody.aspWhen you visit this site, click on English or Spanish, and then sit back and enjoy theshow. This site only covers the brain, skeleton, heart, and digestive tract, but its clear,concise three-dimensional representations of these organs and systems make it wortha look.Drilling, Drilling, Drilling Some Morematcmadison.edu/faculty/cshuster/wiley.htmlThis Web site links to an extensive set of anatomy drill and practice exercises main-tained by John Wiley and Sons (who also happens to be the publisher of this book).To work through the multiple-choice practice questions, you need to download theShockwave plug-in (if you don’t already have it), but that’s a small price to pay forsuch a useful site. Full-color images with blank labels give you the opportunity tofigure out which part is what and why; then you can clear your labels and begin againas often as you like.Human Biodyssey: Exploring Anatomy and Physiologywww.gwc.maricopa.edu/home_pages/crimando/jcHumanBiodyssey.htmThis page is the impressive work of Dr. James Crimando at Gateway CommunityCollege in Phoenix, Arizona. Dr. Crimando lists every scrap of information a studentneeds to succeed in his classes (or any anatomy and physiology class), includingextensive practice questions, lecture outlines, and quick summaries of class sessions.Regardless of whether you’re among Dr. Crimando’s students, his site is an incrediblyuseful receptacle for information about how the body is organized.List of Listswww.mhhe.com/biosci/ap/saladin/www.mhtmlTextbook author Kenneth Saladin uses a small portion of this site to provide descrip-tions of the last three versions of his anatomy and physiology textbooks. But thatdoesn’t begin to compare with what he has done pulling together resources from allover the Web in the Student Resources page we guide you to here. So much to see, solittle time!289Chapter 18: Ten (Plus One) Terrific Online Resources
