The musculi intertransversarii ( Latin for "intervertebral process muscles ", singular musculus intertransversarius ) are a group of skeletal muscles that belong to the intertransversal system ( Systema intertransversale ) of the "local back muscles" . These are muscles that connect the transverse processes of the vertebrae and thus give the spine strength. In the case of one-sided contraction, they cause the spine to tilt sideways, and in the case of bilateral contraction, they also cause a reclination (dorsiflexion).

These muscles can be further divided depending on their location:

The intertransversarii mediales lumborum muscles connect the accessorii processes and teat processes of adjacent lumbar vertebrae .
The intertransversarii laterales lumborum muscles connect the transverse processes of neighboring lumbar vertebrae and, strictly speaking, are not part of the autochthonous back muscles. They can be seen as analogues of the intercostal muscles.
The intertransversarii thoracis muscles connect the transverse processes of adjacent thoracic vertebrae , but are usually absent.
The intertransversarii anteriores cervicis muscles connect the anterior tuberosities of adjacent cervical vertebrae and, strictly speaking, are not part of the autochthonous back muscles. They can be seen as analogues of the intercostal muscles.
The intertransversarii posteriores cervicis muscles connect the tubercula posteriora of adjacent cervical vertebrae.

The innervation is provided by the dorsal rami of the spinal nerves C1 – C6 and L1 – L4. Musculi intertransversarii anteriores cervicis and muscles intertransversarii laterales lumborum are supplied by the corresponding rami ventrales.
