The rectus abdominis muscle is innervated by the thoracoabdominal nerves, which originate from the spinal nerves T7-T12. The other three abdominal muscles (transversus abdominis, internal oblique, and external oblique) are innervated by the lower thoracic nerves (T7-T12), the subcostal nerves, and the iliohypogastric and ilioinguinal nerves (T12-L1), respectively.
