Reflex Action in Animals (explained with diagram) A simple reflex arc (monosynaptic) involves a sensory or afferent neuron, an interneuron present within the spinal cord and a motor or efferent neuron. The afferent is connected to the receptors (such as skin) and the efferent is connected to the effectors (muscles or glands).
