The psoas minor bilaterally. The psoas major has been ghosted in on the right side.

  • The psoas minor attaches from the anterolateral bodies of T12 and L1 to the pelvic bone.



  • The psoas minor flexes the trunk at the spinal joints and posteriorly tilts the pelvis at the lumbosacral joint.


NOTE: The psoas minor should not be confused with the psoas major.
