In your diagram above, how many synapses of the reflex arc are found in the CNS?
Is the reflex monosynaptic or polysynaptic
There should be two synapses in the CNS
the reflex is polysynaptic

What happened to the response when the seated person was naming bones?
There should have been a stronger response (a more pronounced kick). this may or may not have actually been observed.
The brain may send inhibitory signals to the neurons involved in a reflex. Distracting the brain with a task like naming bones may remove theşe inhibitory signals. Given this information, what should happen to the response when the seated person is naming bones?
If inhibitory signals are removed, then there should be a stronger response

Can you identify another autonomic reflex? (Hint: Think of food.)
