Question

13 multiple choice 1 point which of the following is the origin for the quadratus lumborum? iliac fossa 11 - 12th posterior ribs posterior iliac crest 8 - 10th posterior ribs clear my selection

Explanation:

The quadratus lumborum muscle has its origin at the posterior iliac crest. The iliac fossa is not the origin of this muscle. The 11 - 12th posterior ribs are the insertion site (not origin) for some fibers of the quadratus lumborum (it also inserts on the transverse processes of lumbar vertebrae). The 8 - 10th posterior ribs are not related to the origin of the quadratus lumborum.

Answer:

Posterior iliac crest
