The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine. The erector spinae muscles function to straighten the back and provide for side-to-side rotation. An injury or strain to these muscles may cause back spasms and pain.

Which action do all the erector spinae muscles perform?
All of the erector spinae muscles work bilaterally to extend the spine. Longissimus thoracis and longissimus cervicis also function unilaterally to laterally flex the spine to the same side. Longissimus capitis functions unilaterally to rotate the head to the same side.
