Muscle parts
None
Latin name
Musculi rotatores lumborum
Latin muscle parts
None
Group
Epaxial muscle – Transversospinales – Rotatores
Etymology
The English name of this muscle is the muscle that turns (the vertebra) around in the loin region. Rotatores comes from the Latin verb rotatore meaning “to rotate,” which in turn comes from the Latin rota meaning “wheel.” The word lumborum comes from the Latin lumbus, which means the “loin.”
Origin
Mamillary process of lumbar vertebra
Insertion
Inferior margin on the lateral aspect of the lamina of the superjacent lumbar vertebra
Action
Possibly weakly assist with extension of the lumbar vertebrae. They are most likely proprioceptive transducers that monitor the position and movements of the vertebral column and provide feedback that influences the activity of the larger multisegmental muscles of the vertebral column.
Nerve supply
Dorsal rami of lumbar spinal nerves (L2 to L5)
Blood supply
Dorsal branches of the lumbar arteries from the aorta.
Latin
Musculi rotatores lumborum
French
Muscle rotateurs des lombes
