The femoral nerve (L2, 3, and 4) is the largest branch of the lumbar plexus. It runs downward and laterally between the psoas and the iliacus muscles and enters the thigh behind the inguinal ligament lateral to the femoral vessels and the femoral sheath. The ilioinguinal nerve passes through the inguinal canal to supply the skin of the groin and the scrotum or labium majus.ħ The lateral cutaneous nerve of the thigh crosses the iliac fossa in front of the iliacus muscle and enters the thigh behind the lateral end of the inguinal ligament close to the anterior superior iliac spine.Ĩ The lateral cutaneous nerve of the thigh supplies the skin over the lateral surface of the thigh.ĩ It supplies the iliacus muscle in the abdomen The Iliohypogastric nerve (L1), Ilioinguinal nerve (L1), Lateral cutaneous nerve of the thigh (L 2 & 3), and Femoral nerve (L 2, 3 & 4)ĥ The iliohypogastric and ilioinguinal nerves (L1) enter the lateral and anterior abdominal walls.Ħ The iliohypogastric nerve supplies the skin of the lower part of the anterior abdominal wall, and The branches of the plexus emerge from the lateral and medial borders of the muscle and from its anterior surface.ģ The upper two anterior rami give off white rami communicantes to the sympathetic trunkĪll anterior rami receive gray rami communicantes from the sympathetic trunkĤ The nerves that emerge from the lateral side of the psoas major from above downward are: Saeed Makarem"- Presentation transcript:Ģ The lumbar plexus, which is one of the main nervous pathways supplying the lower limb, is formed within the psoas major muscle from the anterior rami of the upper four lumbar nerves.
