Intercostal Nerves

Intercostal nerves is the name given to the anterior primary rami of the upper 11 thoracic spinal nerves (T1 T11) as they use the route through the intercostal spaces. The thoracic wall is supplied by the 12 pairs of the thoracic spinal nerves. Anterior and posterior rami

It’s the ventral ramus of the 12th thoracic spinal nerve. It enters the abdomen behind the lateral precise ligament (lateral lumbocostal arch) and runs downward and laterally in front of the quadratus lumborum below the anterior layer of thoraco-lumbar fascia. At the lateral border of quadratus lumborum,
