Also known as GO:0060004, reflex or spinal reflex, reflex action, involuntary action

In biology, a reflex, or reflex action, is an involuntary, unplanned sequence or action and nearly instantaneous response to a stimulus. thumb|429x429px|The simplest reflex is initiated by a stimulus, which activates an afferent nerve. The signal is then passed to a response neuron, which generates a response. Reflexes are found with varying levels of complexity in organisms with a nervous system. A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to

A reflex is an automatic, nearly instantaneous response to a stimulus that your body produces without you having to think about it, controlled by your nervous system. Reflexes matter because they allow organisms to respond quickly to potentially dangerous situations or stimuli through direct neural pathways called reflex arcs, without waiting for conscious deliberation.
