"origin: thoracolumbar fascia, inner lip of the anterior two-thirds of the iliac crest, lateral third of the grooved upper surface of inguinal ligament, 12th rib, and costal cartilages of 7th-12th ribs where it interdigitates with fibres of the diaphragm."
"insertion: anterior aponeurosis, ending in the linea alba and pubic crest"
"innervation: anterior rami of spinal nerves T7-L1"
"blood supply: posterior intercostal and subcostal arteries, superior and inferior epigastric arteries, superficial and deep circumflex iliac arteries, posterior lumbar arteries"

"It is innervated by the terminal branches of intercostal nerves T7-T11, the subcostal nerve (T12), the iliohypogastric nerve (L1) and ilioinguinal nerves (L1). These nerves arise from the ventral rami of the spinal nerves of T7-L1, and this is the simplified description of innervation described in anatomy textbooks."
