A reflex occurs in what is called a reflex arc that involves the following anatomy in order: Receptor: The dendrite of a neuron receiving the stimulus Afferent neuron (sensory) that has an action potential carrying the signal to the CNS. Integrating center: either the brain or spinal cord where the signal is received from the afferent neuron and conducted to a motor neuron. This may or may not require an interneuron. Efferent neuron (motor) that has an action potential carrying a signal away from the CNS. Effector: the structure causing the effect. If this structure is skeletal muscle, it is called a somatic reflex. If the effector is a gland or smooth muscle, it is called an autonomic reflex.
