Q

In spinal cord compression, which symptoms come first: sensory symptoms or motor symptoms?
- why is this

A

Motor symptoms come first
- cancer usually comes from the vertebral body (remember the vertebral body is positioned anterior to the SC) and the cancer works posteriorly so it hits the ventral horn first (motor) before the dorsal horn (sensory)
