the knee-jerk reflex
knee jerk
No, those are two different reflexes.
The patellar ligament initiates the knee jerk reflex when tapped. When the patellar tendon is tapped just below the patella, the sensory neurons detect the sudden stretch and send an impulse to the spinal cord. This reflex causes the contraction of the quadriceps muscles, resulting in the extension of the leg.
The reflex arc is the nerve pathway that the signal follows. For example, the knee jerk reflex arc has a stimulus going to an interneuron in the spine and a motor neuron completes the arc by causing the knee to jerk. A reflex is just the action itself.
