  • Students with motor weaknesses may have some difficulty with the zoom and rotational options.

Mindprint Expert Review

Essential Skeleton4 is an excellent resource for any student studying anatomy or human biology. The homescreen is a full body 3D skeleton which students can zoom in and out to focus on a specific bone or region. Individual or multiple bones can be selected and "pinned" with notes and bookmarked. There is a pen for students to draw/take notes on any screen and save. Students can choose to read about a bone, have the name pronounced, view related structures, isolate bones or multiple bones, take notes, and take a quiz. The quizzes have an optional timer, choice to include Latin subtitles, and can be "drag and drop" or multiple choice. Views of structures can be shared via email, Facebook, Twitter, or an image can be saved to iPhoto. Students can also choose to search via text rather than by clicking on the specific bone. The explanations are written in a very understandable way, although the vocabulary can be challenging and there is no option for further explanation. This is a great app for beginning anatomy students to visualize the skeletal system and improve their understanding and even better for advanced students to deepen and test their knowledge with the built-in quizzes.
