The 3D model can be simply manipulated using finger gestures: spread to zoom in; drag two fingers to pan; pinch to zoom out; and drag to rotate.
Tap on a structure to select it, and to access the view options for each structure.
When a structure is selected, the path of that structure is revealed along the top of the screen, as part of the breadcrumb trail. The parent of the highlighted structure may be selected simply by tapping on its name, and can in turn be manipulated as a structure in its entirety.
Turning Systems On and Off
There are nine systems in Essential Anatomy; muscular, skeletal, veneral, arterial, nervous, respiratory and digestive. Muscle layers can be added or removed by tapping the 'Add Muscle' or 'Remove Muscle' icons.
