I just used Google Lab’s Body Browser to identify the nerve causing persistent problems for Ladybug. You can vary the opacity of the circulatory, muscular, skeletal and organ systems as well as rotate and magnify the body with the option of labels. [More at ZDNet]
Clicking on a specific part of interest, e.g. the femoral nerve in this case, results in it being highlighted and labelled. This specific view is mapped by the URL, so the specific view can be forwarded to someone else.
As it requires WebGL support, you will need to replace Google’s Chrome browser with a beta version; similar options for other browsers are listed at khronos.org. Once you have a WebGL-enabled browser, go to bodybrowser.googlelabs.com and have fun exploring this lovely tool which will become indispensable in many classrooms!
