Nerve Innervation of the Rectus Femoris Primary Nerve Supply: • Femoral Nerve (L2, L3, L4) Origin of the Femoral Nerve: • The femoral nerve arises from the lumbar plexus (ventral rami of L2–L4). • It passes through the psoas major muscle and emerges from its lateral border. • It then descends between the iliacus and psoas major, traveling under the inguinal ligament to enter the femoral triangle in the anterior thigh. Branches Supplying Rectus Femoris: • The muscular branches of the femoral nerv

⚡ The Femoral Nerve: The Key to Thigh Movement and Sensation ⚡ The femoral nerve originates from the lower spine (L2-L4) and plays a major role in: Movement: Powers the quadriceps for knee extension and hip flexion. Sensation: Provides feeling to the front of the thigh and inner leg. When damaged, the femoral nerve can lead to weakness, numbness, and mobility challenges.
