Intertransversarii muscles

The intertransversarii muscles are small and short deep back muscles that stretch between the transverse processes of the adjacent vertebrae. Most of these muscles are located in the cervical (intertransversarii cervicis muscles) and lumbar (intertransversarii lumborum muscles) regions of the spine. However, small muscular slips are present in the lower thoracic region (intertransversarii thoracis muscles). Together with the interspinales muscles and levatores costarum muscles, the intertransversarii form the deepest layer of the deep back muscles.
