The erector spinae is not just one muscle, but a bundle of muscles and tendons which run more or less vertically and are paired left to right. These muscles lie in the groove to the side of the vertebral column and extend throughout the lumbar, thoracic, and cervical regions
If the erector spinae muscle is too tight or contains tender or trigger points it may limit certain movements or make them highly unpleasant.
This large muscular and tendinous mass varies in size and structure at different parts of the vertebral column. In the sacral region, it is narrow and pointed, and at its origin chiefly tendinous in structure. In the lumbar region, it is larger, and forms a thick fleshy mass. Further up, it is subdivided into three columns. They gradually diminish in size as they ascend to be inserted into the vertebrae and ribs.
