Iliocostalis Lumborum belongs to the lateral column of the Sacrospinalis group of muscles.[1]
Origin[edit | edit source]
Anterior surface of a broad and thick tendon w attached to the medial crest of sacrum, spinous processes of the lumbar vertebrae, 11th and 12th thoracic vertebrae, posterior part of the medial lip of iliac crest, supra-spinous ligament and the lateral crest of sacrum[2].
Insertion[edit | edit source]
By tendons into inferior borders of the angles of the lower 6 or 7 ribs[2][3]
Nerve Supply[edit | edit source]
Dorsal rami of thoracic and lumbar spinal nerves (T7 to L3)[4]
Blood Supply[edit | edit source]
Dorsal branches of the lumbar arteries from the aorta. Dorsal branches of the lateral sacral artery from the internal iliac artery.[4]
Action[edit | edit source]
- acting bilaterally, extension and hyperextension of the spine
- acting unilaterally, laterally flexes the spine[3]
- assists as an accessory muscle of expiration, due to its insertion on the ribs[5].
Function[edit | edit source]
