Trunk · Posterior abdominal wall
Psoas major belongs to the posterior abdominal wall and crosses into the hip region. Choose a side to open its existing 3D model and anatomy guide.
Inspect the isolated muscle, read its anatomy guide, or restore both psoas muscles and the available trunk bones. No duplicate article or model is created for this region.
