The knee reflex is also called the knee-jerk reflex by tapping the patellar tendon with a reflex hammer. This sends sensory information to the spinal cord at L4 and motor information back to the Quadriceps in the thigh (relaxing the hamstrings). This is reflex requires only two neurons. No interneuron. And so is very rapid. It is important in balance and posture.
