User interfaces facilitate user interaction with virtual representations of anatomical structures that are displayed on computing systems. The user interfaces demonstrably reflect the relative impact of different medical conditions on the anatomical structures. The impact of the medical conditions can be reflected in real-time, as a slider object is manipulated to pull a slide transition screen over the anatomical object. Portions of the anatomical object that become overlapped by the slide transition screens are displayed with dynamic modifications that reflect the impact of the medical conditions associated with the slide transition screens.
