Question

Quizplus · Accepted Answer

The patellar reflex, also known as the knee-jerk reflex, is a reflex arc that involves the activation of the quadriceps muscle, which causes the lower leg to extend or come forward in response to the tap on the patellar tendon. The hamstring muscle, located in the back of the thigh, is not involved in this reflex.
