The sartorius muscle is the only muscle listed that crosses and produces actions at two joints. It originates from the anterior superior iliac spine and runs diagonally across the thigh to insert on the medial surface of the tibia. It crosses both the hip and knee joint and produces actions at both joints. It flexes the hip and knee, abducts and laterally rotates the hip, and assists in medially rotating the tibia.
