buttocks

these rounded projections are formed mainly by the three gluteal muscles. They arise from the surface of the ilium of the hip bone and cross the back of the hip joint to be inserted into the femur. The gluteus maximus, the largest, is crucial in the maintenance of the upright posture, as an extensor at the hips, and also in running, climbing and walking up steps. It also assists in keeping the leg straight at the knee, via a fibrous band attached to the tibia. The two smaller muscles (g. medius, g.minimus) mainly take part in abduction and rotation at the hip. Figure 1.
