Konnaiyan Patellar reflex: Patellar reflex is contributed by 3rd and 4th Lumbar segment nerves‚ in some cases 2nd lumbar segment is also involved. So an individual will be left with patellar reflex if these lumbar vertebrae are left intact. Patellar reflex is also called knee-jerk reflex as the names implies‚ it is involved with tapping of knee at certain point will cause a jerk movement. In medical terms when an individual is tapped on patellar tendon (area below the knee cap) using a reflex hammer‚ it

Discussion In the patellar reflex experiment‚ the class results have shown the reaction is faster with performing the Jendrassik’s maneuver. Our group hypothesis was proven incorrect. The source of error in this experiment would be the subject can easily control the skeletal muscles which would be voluntarily because the subject was not blindfolded. Therefore‚ the subject can see the rubber coming at their knee and is expecting the knee to jerk. It’s hard to consider this exact result when the subject
