Apps such as Essential Anatomy 5 give users a seamless and fluid 3D experience. Available on iTunes ($24.99), Essential Anatomy 5 contains more than 8,200 highly-detailed anatomical structures.

The app has 11 complete systems (all accessible from the main screen); Muscular, Skeletal, Connective Tissue, Venous, Arterial (including the Heart), Nervous (including the Brain), Respiratory, Digestive, Lymphatic, Urogenital and Skin.

Along with the structures, each entry includes a detailed description, an audio English pronunciation and Latin nomenclature. There are comparison tools available so individuals can isolate single or multiple structures and compare them with others.

Users can create and save custom views with the bookmark feature and the pin feature that lets individuals make customized pins, add notes, and place anywhere on the 3D model.

In addition, the app lets individuals explore and compare differences between male and female anatomy. And, the app's layering tool allows the user to strip away layers of muscle.

The app is available for iPads, iPhones (iOS7+) and Macs (OSX 10.8+).
