Protective reflexes are automatic, involuntary responses of the nervous system that help prevent injury or harm to the body by quickly responding to potentially dangerous stimuli. They are essential for survival and include reflexes like blinking, coughing, and the withdrawal reflex, all of which are mediated by neural pathways that bypass conscious thought to ensure rapid reaction times.
