Funke a 19 year old student was climbing a rock with his friend when he fell 30 feet to the ground. Paramedics found him lying supine at the scene, he was awake but unable to move all his limbs. A physical examination four days later revealed normal vital signs but no change in his arm strength or sensation. Moreover, he showed spasm and exaggerated stretch reflexes of the lower extremity. Funke also had to use a urine bag due to urinary incontinence. Based on the physical examination and the findings, which vertebrae do you think was fractured, explain why you think so. Four days after the accident, funke arms were still flaccid as opposed to his lower limb muscles, which were spastic with exaggerated stretch reflexes, can you explain this?
