Reflex Lab

Neuromuscular Reflexes Lab\

 

In this lab there was a group of us and we recorded the results from tapping the patellar tendon below the knees with a reflex hammer. This motion caused the quadriceps muscle to contract and the leg would then kick up. When the muscles stretch nerve impulses travel to the spinal cord Motor neurons would then activate and go back to the muscle for the muscle contractions

 

Procedure:

So to begin with we grab a computer and connect the EKG Sensor to the computer, then attach two of the electrode tabs above to subjects knee. The last one should then be placed on the lower leg. The three colored cords should be connected correctly, the red and green should be connected to the electrodes above the knee, the black then connected to the electrode below the knee. Tap the subject with the reflex hammer, then record the voluntary activation data. Afterwards record the patellar reflex  data and the patellar reflex data with reinforcement.
