– The receptor detects the stimulus.
– The sensory (afferent) neuron transmits the impulse from the receptor towards the central nervous system (CNS).
– The integration center (in simple reflexes, often the spinal cord) processes the signal.
– The motor (efferent) neuron transmits the impulse from the CNS to the effector.
– The effector (muscle or gland) carries out the response.
