The ______________ has the origin on the iliac crest and the insertion on rib 12 and L1-L4 vertebrae.

Answers

Answer:

Quadratus lumborum

Explanation:

Quadratus lumborum, commonly known as back muscle is a posterior abdominal wall muscle. The shape of the muscle is irregular as well as quadrilateral and broader below than above and is the the deepest abdominal muscle.

The muscle originates by the aponeurotic fibers into iliolumbar ligament and internal lip of iliac crest for about 5 centimeters . It then inserts from the lower border of last rib (rib 12) for about the half of it's length and also by the four small tendons from apices of transverse processes of upper four lumbar vertebrae. (L1-L4).

Final answer:

The Quadratus Lumborum muscle originates from the iliac crest and has its insertion on rib 12 and L1-L4 vertebrae. This muscle aids in spinal extension and lateral flexion of the lumbar spine.

Explanation:

The muscle that has its origin on the iliac crest and its insertion on rib 12 and L1-L4 vertebrae is the Quadratus Lumborum muscle. The Quadratus Lumborum originates from the iliac crest, specifically the posterior third portion, and it inserts at the twelfth rib and the transverse processes of the L1-L4 vertebrae. The role of this muscle is to aid in spinal extension and lateral flexion of the lumbar spine. When the muscle contracts bilaterally, it helps with lumbar extension (back extension) and when it contracts unilaterally, it aids in lateral flexion of the spine (sideways bending).
