The concept of a reflex
... To help an organism avoid injury reflex arcs provide a means for immediate withdrawal from dangerous stimuli. While all sensory information does eventually get sent to the brain for analysis, the advantage of a reflex arc is that it can process the rapid, protective response directly in the spinal c ...
