Neural anatomy of the lower limb features nerves that innervate the muscles and skin, providing motor and sensory functions. The lumbar and sacral plexuses give rise to major nerves, including the femoral, sciatic, and obturator nerves. The femoral nerve innervates the anterior thigh muscles, while the sciatic nerve, the largest nerve in the body, supplies the posterior thigh, leg, and foot. The obturator nerve innervates the medial thigh muscles. Detailed 3D visualizations trace the paths of these nerves, emphasizing their functions and potential sites of injury.
