If a doctor attempts to trigger the patellar tendon reflex and a lack of response occurs, what are potential regions where pathology might exist? I) the brain II) the knee III) the spinal cord A. only I B. only II C. only III D. only II and III

A kicking-like action is created by the extension of the knee joint in response to ipsilateral stimulation of the patellar tendon and is known as the patellar tendon reflex.
It is believed that the reaction aids in keeping one's balance.
Stretching the quadriceps muscle spindle involves striking the patellar tendon directly below the patella using a reflex hammer.

What is pathology?

The field of medicine called pathology offers patients and clinicians diagnostic data. It affects almost every facet of patient care, from cancer diagnosis to the management of chronic diseases through precise laboratory testing. The quadriceps, a group of muscles at the front of the upper leg, are gently stretched by the quick tap on the tendon. These muscles tighten in response, which usually causes the leg to straighten and kick. Exaggeration or lack of a response indicates that the central nervous system may have been damaged.
