Sally, 9-year-old girl, just did an awesome backflip on her trampoline. Instead of landing in a similarly awesome manner, she miscalculated and landed on her neck. Sally stood up with pain in her neck and her pride left on the trampoline, and does not appear to be able to extend her left arm very well. An X-ray shows a fracture of her C6 vertebrae that is compressing down on her C7 vertebrae. Which spinal nerve did Sally likely lesion? a) Left C6 spinal nerve
b) Right C7 spinal nerve
c) Right C6 spinal nerve
d) Left C7 spinal nerve
