Why doesn''t the patellar reflex happen when your leg is straight?

The patellar reflex can be defined as the kicking movement of the lower leg which occurs with a sudden twitch when the patellar tendon of a person is tapped. This patellar tendon is present below a person's kneecap. This reflex happens only when the leg is bended. It is impossible for patellar reflex to occur if the leg is straight as the quadriceps muscles are already contracted and a sudden kicking movement of the leg in such state could not be elicited.  The patellar reflex protects the quadriceps  from stretching too much.

The patellar reflex doesn't happen when our leg is straight because tendon will not be flexible.

When our leg is straight, it doesn't happen. It only happens when tendon is flexible.

This reflex helps us maintain posture and balance,
allowing one to walk without consciously thinking about each step.

Answer:Each of us has the power, through our own choices and actions, to save American lives and rescue the most vulnerable among us.

That’s why we really have to do what we all know is right.  Every citizen is being called upon to make sacrifices.  Every business is being asked to fulfill its patriotic duty.  Every community is making fundamental changes to how we live, work, and interact each and every day, and I wouldn’t be surprised to see this going on long into the future, when this virus is gone and defeated.  Some of the things we’re doing now will be very good practice for the future, including for not getting the flu, which is very devastating also.  So some of what we’re learning now will live on into the future — I really believe that: shaking hands or not shaking hands; washing hands all the time; staying a little apart.
