The rotatores longi span two vertebral levels, providing a broader proprioceptive sampling zone than the breves and contributing slightly more to active rotation.
| Origin | Transverse process of each thoracic vertebra |

They provide segmental control and position sense across two thoracic levels, with a small contribution to rotation.
Their asymmetric development on concave and convex sides of a scoliotic curve may contribute to rotational deformity. Their bilateral activation during breathing links thoracic paraspinal function to respiratory mechanics.
Not palpable individually.
