Detailed explanation-1: -The lumbar plexus gives rise to several branches which supply various muscles and regions of the posterior abdominal wall and lower limb. These branches include the iliohypogastric, ilioinguinal, genitofemoral, lateral femoral cutaneous, femoral and obturator nerves.
Detailed explanation-2: -The femoral nerve ranks as the largest nerve that arises from the lumbar plexus. It is created from lumbar spinal nerves L2, L3, and L4. Its principal function is to supply motor and sensory innervation to the anterior compartment of the thigh.
Detailed explanation-3: -The femoral nerve ranks as the largest nerve that arises from the lumbar plexus. It is created from lumbar spinal nerves L2, L3, and L4. It leaves the plexus and enters the femoral triangle, passing just lateral to the femoral artery. Sensory input: anterior compartment of the thigh.
Detailed explanation-4: -The LS plexus gives off the iliohypogastric, ilioinguinal, genitofemoral, obturator, femoral, lateral femoral cutaneous, sciatic common peroneal, tibial, superior and inferior gluteal, pudendal, and posterior femoral cutaneous nerves, as well as motor branches to the psoas and iliacus muscles.
