Explain the medial to lateral placement of the muscle groups of erector spinae

What will be an ideal response?


The three groups of the erector spinae are named in order of their medial-lateral placement relative to the axis of the vertebral column. The spinalis group is located closest to the center of the vertebral column, just to the sides of the spinous processes of the spine. The longissimus group is slightly lateral to the spinalis group. The iliocostalis group is the most lateral.
