Question

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

Answer 1

Option D. Only II and III.(THE KNEE AND THE SPINAL CORD)

What is the patellar tendon reflex?

• The patellar tendon reflex refers to a kicking-like motion produced by the extension of the knee joint upon the ipsilateral stimulation of the patellar tendon.
• The reflex is thought to play a role in maintaining balance

• Striking of the patellar tendon with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle.

What is pathology?

• Pathology is the medical discipline that provides diagnostic information to patients and clinicians.
• It impacts nearly all aspects of patient care, from diagnosing cancer to managing chronic diseases through accurate laboratory testing.
• The sharp tap on the tendon slightly stretches the quadriceps, the complex of muscles at the front of the upper leg
• In reaction these muscles contract, and the contraction tends to straighten the leg in a kicking motion.
• Exaggeration or absence of the reaction suggests that there may be damage to the central nervous system
