The internal abdominal oblique muscle is responsible for lateral flexion of the trunk at the spinal joints, along with rotation and compression of the abdominal contents. Extension of the trunk at the spinal joints is performed by the erector spinae muscles, flexion of the thigh at the hip joint is performed by the iliopsoas muscle, and anterior tilt of the pelvis at the lumbosacral joint is performed by the rectus abdominis muscle.
