3. Examples of each of these are: a. Knee jerk response (simple/spinal cord only)
4. b. Sneezing – one of the reflex centers in the medulla (involves brainstem activity only)
5. c. Hand on a hot stove – a simple reflex pulls the hand away (spinal cord arc only, no brain involvement) followed by a reaction due to an interneuron connection to the brain from the spinal cord.
