Explanation The neural branches from the lumbar plexus are associated with the neural innervation to the lower thigh. The lumbar plexus arises from the first four lumbar vertebrae of the spinal cord. The main branches of the lumbar plexus innervate the anterior region of the thigh. The three nerves that are involved in innervating the muscles of the thigh are listed below: 1. Femoral nerve: This is the largest terminal branch of the lumbar plexus that enters the thigh through the inguinal ligament. The femoral nerve gets divided into several branches from the femoral triangle. Quadriceps femoris and other muscles of the anterior compartment of the thigh are innervated by its motor branch...
