The questions include filling in the names of structures and clicking on the specified structure. The program then gives you a breakdown of your correct and incorrect responses so you can individualize your study. There is also a search function that is easy to use. The only strange thing I noticed on the copy I reviewed was that when you hit the clinical correlation button for the ankle, it gives you the femur instead. All the other areas I tested worked appropriately.
