... 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 200 synapses in a polysynaptic arc In the childish diagram above, some important elements have been omitted: ...
