how did mental distraction and muscle activity in another area affect the patellar knee-jerk reflex?
Added by Krista J.
Step 1
Mental Distraction: Mental distraction can potentially decrease the intensity of the patellar knee-jerk reflex. This is because when the brain is focused on another task, it may not send as strong signals to the muscles involved in the reflex. This can result in a Show more…

With regard to the Knee Jerk Reflex: What is the physiological function of this reflex? Explain how this reflex may be important during walking, if you are clumsy like me and did not notice a hole in the sidewalk and stepped into it. What is the role of reciprocal inhibition? How would the reflex be affected if reciprocal inhibition failed? Describe the effects on the reflex of severing each structure involved in the reflex, considering one structure at a time.

Test the effect of mental distraction on the patellar reflex by adding numbers in your head while you test the reflex again. Did the response change when you were mentally distracted? Why do you think this is so?
