The erector spinae

The erector spinae is not just one muscle, but a bundle of muscles and tendons: Iliocostalis lumborum, Iliocostalis thoracis, Iliocostalis cervicis, Longissimus thoracis, Longissimus cervicis, Longissimus capitis, Spinalis thoracis, Spinalis cervicis, and Spinalis capitis. Paired, they run more or less vertically. It extends throughout the lumbar, thoracic and cervical regions, and lies in the groove to the side of the vertebral column.Erectores espinales

Erector spinae is covered in the lumbar and thoracic regions by the thoracolumbar fascia, and in the cervical region by the nuchal ligament.

This large muscular and tendinous mass varies in size and structure at different regions. 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. These diminish in size as they ascend to be inserted into the vertebrae and ribs.

Some of its fibers are continuous with the fibers of origin of the gluteus maximus.

The erector spinae functions to straighten the back and provides for side-to-side rotation. Also maintains the correct curvature of the spine.
