A knee-jerk reaction is an example of what?

Explanation:
Reflexes are automatic, involuntary responses to a stimulus. A knee-jerk reaction is a classic reflex because it happens quickly without conscious thought and without needing prior learning. The tap on the tendon stretches the quadriceps, sending a signal into the spinal cord where it directly activates a motor neuron to contract the muscle, producing the leg kick. This differs from memory (which involves storing and retrieving information), perception (interpreting sensory input), and learning (changes in behavior due to experience).
