This sensory neuron then relays this information to the central nervous system where afferent neurons synapse with interneurons which in turn synapse with efferent or motor neurons. This motor neuron then relays the information out of the brain to an effector. In this case, the effector is a skeletal muscle that causes the reflex response to occur. Reaction time is a measure of the time between when the stimulus is delivered and the response occurs. This speed can vary person-to-person depending on the speed of transmission of the signal from neuron to neuron, as well as the number of neurons involved (Widmaier
