Oftentimes when we cry, we feel a lump in the throat.
很多時候，當我們哭泣時會喉嚨哽咽。
Does a lump actually form, or is there some other explanation?
難道喉嚨中真的出現了塊狀物？還是有其它的解釋？
The lump-like thing we feel when overcome by emotion has to do with how the nervous system deals with stress.
我們受情緒主導時，所感受到的結塊狀物體與神經系統處理緊張的方式有關。
The part of the nervous system that handles stress is called the autonomicnervous system.
神經系統中處理緊張的部分系統為自主神經系統。
It controls bodily functions that we do not consciously control, such as digesting food and pumping blood through the heart.
它能控制人體無意識會控制的一些身體功能，如消化食物和心臟輸送血液。
However, the autonomic nervous system is also important in dealing with emotional states.
不過，自主神經系統在處理情緒時非常重要。
When an animal encounters a stressful situation, its autonomic nervous system kicks in to allow it to either fight or run away.
當動物身處緊張環境時，自主神經系統開始發揮作用促使動物選擇戰或逃。
