Quizplus · Accepted Answer

The patellar tendon reflex is a spinal reflex that involves the spinal cord and the knee joint. A lack of response could indicate pathology in either the knee joint or the spinal cord. However, it is unlikely to be related to the brain. Therefore, options I and II are not correct while options II and III are potential regions where pathology might exist.
