The Intertransversarii are a group of intrinsic paired-muscles of the spine located between transverse processes, primarily in the cervical and lumbar regions.
ATTACHMENTS:
- Spinous processes of C1 to T2.
- Spinous processes of T10 to L5.
ACTIONS:
- Laterally flexes the neck and lower trunk at the spinal joints.
NOTES:
- The intertransversarii are primarily located in the cervical and lumbar regions. They typically extend down to T2 from the cervical spine, and up to T10 from the lumbar region.
- There is a pair of intertransversarii muscles on each side in the cervical and lumbar regions (anterior and posterior set in the cervical region and medial and lateral set in the lumbar region).
- The intertransversarii between C1 and C2 are often absent.
- Some sources believe that the intertransverarii are more important for proprioception than for actual movement.
