Regions of a sarcomere

The Figure Comparison is a means of stacking two similar visual datasets and traversing between each to affect a comparison. This Interactive Media Object is broken down into; two image figures with alt text and figure caption descriptions, a button to show each figure, and a slider button control all accessible via the Tab key and sliding is available via the Arrow keys.

Electron micrograph of a sarcomere.
