The simplest reflex arc is one where there is just one synapse between the afferent and the efferent neurons This is what you call a MONOSYNAPTIC arc If there are any interneurons in the way between the afferent and the efferent neurons, this is called a POLYSYNAPTIC arc. There can be anywhere up to ...
