Their combined action is rotation and extension of the vertebral column. These muscles are small and have a poor mechanical advantage for contributing to motion. They include: the three semispinalis muscles, the multifidus muscle, and the rotatores spinae muscles.
==Location==
The three semispinalis muscles, span 4-6 vertebral segments: ** semispinalis thoracis ** semispinalis cervicis ** semispinalis capitis
The multifidus muscle, and spans 2-4 vertebral segments
The rotatores muscles, lie beneath the multifidus, and spans 1-2 vertebral segments ** rotatores cervicis ** rotatores thoracis ** rotatores lumborum
