Transversospinales

The transversospinales are a group of muscles of the human back. 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, 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
