Why are the reflex actions controlled by the spinal cord and not the brain?

A reflex action often involves a very simple nervous pathway called a reflex arc. A reflex arc starts off with receptors being excited. They then send signals along a sensory neuron to your spinal cord, where the signals are passed on to a motor neuron. Reflex action is an involuntary and nearly instantaneous movement in response to a stimulus. Invertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. The spinal cord acts as the main centre for reflex actions. The spinal cord acts as a link between spinal nerves and the brain.
