Etymology
In English, this muscle’s name is the middle muscle between the crosswise processes of the loin vertebrae. The word intertransversarii comes from the Latin inter meaning “between” and the Latin term transversus for “crosswise,” which comes from Latin trans meaning “across, beyond, or through” and the Latin verb vertere meaning “to turn.” It is used in reference to the transverse processes of the vertebrae.Lumborum comes from the Latin lumbus for “loin.”The Latin term medialis is derived from the Latin medius meaning “middle.”
Origin
Accessory processes of lumbar vertebrae two through five
Insertion

Dorsal rami of lumbar spinal nerves (L1 to L5)
