面對壓力或危險時自動反應的神經系統

the sympathetic nervous system

用法筆記

The sympathetic nervous system works automatically — you cannot control it by will. It is one of two branches of the autonomic nervous system; the other is the parasympathetic nervous system, which controls rest and digestion. In everyday English, people often describe its effects as an 'adrenaline rush.'
