A ____________ is the simplest of all reflexes. The ____________ axons synapse directly on the ____________ neurons, whose axons project to the ____________ . Very minor synaptic delay is incurred in the single synapse of this reflex arc, resulting in a ____________ reflex response. A ____________ has more complex neural pathways that exhibit a number of synapses involving ____________ within the reflex arc. Because this reflex arc has more components, a more ____________ delay occurs between stimulus and response
