What type of reflex is the knee-jerk reflex?

Step 1: Understand what a reflex is. A reflex is an automatic response to a stimulus.
Step 2: Learn about the knee-jerk reflex. This is a specific reflex that happens when you tap below your knee.
Step 3: Identify the type of reflex. The knee-jerk reflex is called a monosynaptic reflex.
Step 4: Know what monosynaptic means. It means there is only one connection (synapse) between two neurons.
Step 5: Recognize the neurons involved. In the knee-jerk reflex, a sensory neuron detects the tap and sends a signal directly to a motor neuron.
Step 6: Understand the result. The motor neuron then causes the muscle in your leg to contract, making your knee jerk.
