The integration center is the only portion of a reflex arc that is found entirely within the CNS. It receives and processes sensory information from the sensory neuron and sends out motor commands via the motor neuron. The receptor is the structure that detects the stimulus, the sensory neuron carries information from the receptor to the integration center, the motor neuron carries information from the integration center to the effector, and the effector is the structure that carries out the motor response.
