Fig. 2. A schematic right lateral view of major movements of the right femur. The most dorsal rectangular box represents the pelvis. The long cylinder attached to the pelvis is the femur. The small rectangle on the femur represents the greater trochanter, which is parallel to the black reference line on the distal end of the femur. The more distal cylinder represents the lower leg, and the most ventral rectangle represents the tarsals and metatarsals. For each pair of figures in a row, the figure on the right illustrates the movement relative to the initial position shown on the left. For the sake of simplicity, rotation of the pelvis in the horizontal plane is not shown, but this movement occurs in most lizards and salamanders.
