- the three semispinalis muscles, spanning 4-6 vertebral segments
- semispinalis thoracis
- semispinalis cervicis
- semispinalis capitis
- multifidus, spanning 2-4 vertebral segments
-
rotatores, spanning 1-2 vertebral segments
- rotatores cervicis
- rotatores thoracis
- rotatores lumborum
- interspinales
- intertransversarii
