Flatrock Pressure Point Control Tactics (PPCT) Practice Test

The key idea is how the body decides to switch on the fight-or-flight response. The sympathetic nervous system (SNS) is activated by cues that demand rapid action and heightened alertness. Objective threat perceptions and objective fear perceptions are direct signals of danger. When you clearly sense a threat or feel fear, the body gears up, adrenaline rises, heart rate increases, and muscles ready for action—that’s SNS activation in action. Physical exhaustion also pushes the system toward SNS readiness. When the body is taxed and needs to keep functioning, the SNS helps mobilize energy and sustain performance. Sleep deprivation, while it can worsen stress and impair judgment, isn’t considered a direct trigger for initiating the SNS in this framework. It’s a condition that can degrade performance and increase baseline arousal over time, but it doesn’t by itself cue the immediate fight-or-flight response the way the other factors do. So sleep deprivation is the one that does not fit as a trigger for SNS activation in this context.
