It incorporates the abdominal proper cavity (including the volume of the false pelvis), contents and wall including the lumbar vertebral column and all the overlying muscles, skin and subcutaneous tissue. It consequently includes the intra-abdomen proper structure, the anterior abdominal wall and the posterior lumbar region. Note, the entire bony pelvis although forming part of the boundary is excluded from the abdomen proper segment of trunk (but is included as part of the pelvic segment of trunk).\Structure of lumbar region of back\This volume includes the lumbar segment of the spinal column, its spaces and contents, notably the spinal canal, spinal meninges and spinal cord within this segment.
