|
|
Which spinal nerves form the lumbar plexus? |
Anterior rami of L1-L4 (with contributions from T12) |
|
|
Describe the course of the iliohypogastric nerve? |
. It runs to the iliac crest,
. across the quadratus lumborum muscle of the posterior abdominal wall. . It then perforates the transversus abdominis, and divides into its terminal branches. |
|
|
What is the root of the iliohypogastric nerve? |
L1 (with contributions from T12) |
