Quadratus Lumborum Anatomyzone Quadratus lumborum originates from the iliolumbar ligament and iliac crest. it runs craniomedially, attaching to the inferior border of 12th rib and the transverse processes of the 1st to 4th lumbar vertebrae. all fibers together give the muscle a rectangular appearance. The anatomy texts describe the quadratus lumborum muscle as an extensor of the lumbar spine, a stabilizer of the lumbar area, capable of pelvic tilting laterally and capable of acting as an inspiratory accessory muscle.
Quadratus Lumborum Anatomy The quadratus lumborum is a muscle in the posterior inferior trunk lateral to the spine (see image. abdominopelvic muscles). this muscle attaches to the iliac crest, the transverse processes of lumbar vertebrae 1 to 4, and the 12th rib. The quadratus lumborum is a muscle of the posterior abdominal wall. it is a thick muscular sheet, quadrilateral in shape, and positioned superficial to the psoas major. attachments: originates from the iliac crest and iliolumbar ligament. Each muscle of the pair is an irregular quadrilateral in shape, hence the name. the quadratus lumborum muscles originate from the wings of the ilium; their insertions are on the transverse processes of the upper four lumbar vertebrae plus the lower posterior border of the twelfth rib. The quadratus lumborum runs vertically and slightly posteriorly in the posterior abdominal wall. it traverses a path from its origin points at the iliac crest and lumbar vertebrae and ascends towards its insertions at the ribs and transverse processes of the lumbar vertebrae.

What is quadratus lumborum? the quadratus lumborum is one of the deepest abdominal muscles and is commonly referred to as a back muscle. it is located in the posterior abdominal wall on either side of the lumbar spine and is irregular and quadrilateral in shape. Learn what is the quadratus lumborum muscle & its anatomy: where it is located, attachments, what functions does it do, nerve, blood supply, with picture. Learn about the quadratus lumborum muscle's origin, insertion, actions, and its role in trunk extension and lateral flexion. The quadratus lumborum muscle is a paired, irregular quadrilateral muscle that forms part of the posterior abdominal wall. summary origin: transverse process l5 vertebra, iliolumbar ligament and internal rim iliac crest insertion: transverse p.
