A mоther brings her 8-yeаr-оld sоn to the clinic. Three dаys eаrlier he and another child had been “sword fighting” with wooden swords. The boy received a sharp blow to his right lower extremity, and since then his foot has “dragged” when he walks. Physical examination shows that he can raise up on his toes, but cannot walk on his heels. Further testing shows that he cannot dorsiflex his right foot. Sensation is intact on the foot, except for numbness of the web space between the first and second digits. At what spinal level are the cell bodies that give rise to the motor axons (GSE) that were damaged?
