Choose an Action View by first tapping on the " Actions" option on the Home screen, then choosing a region, and then tapping on a thumbnail. An interactive animation is launched, demonstrating the action on a continuous loop. The model can be adjusted with your fingertips to a different size or angle while playing or while paused (see "Adjusting Views" section.) The buttons at the left of the screen provide different perspectives of the muscle action, showing some of the muscles involved in the actions faded so that deeper muscles can be better viewed. The first button is the default View that is first launched.
Above the View buttons are "Define," which defines a highlighted muscle, and "Action Info," which provides the names of the muscles involved in the action.
On-screen muscles and bones can be identified by tapping on the structure. It is selected, highlighted, and the name is shown at the top of the screen.
By tapping on the speaker icon to the right of the name, you can hear the pronunciation. Tap the Definition icon to view the muscle's definition.
The action can be paused by tapping on the "Pause" button at the bottom of the screen and restarted by tapping on the "Play" button. The looping functionality can be stopped by tapping on the "Loop" button to turn the icon black; tapping the icon again turns it to gray and reverts back to the looping function.
