Oftentimes when we cry, we feel a lump in the throat.
很多时候，当我们哭泣时会喉咙哽咽。
Does a lump actually form, or is there some other explanation?
难道喉咙中真的出现了块状物？还是有其它的解释？
The lump-like thing we feel when overcome by emotion has to do with how the nervous system deals with stress.
我们受情绪主导时，所感受到的结块状物体与神经系统处理紧张的方式有关。
The part of the nervous system that handles stress is called the autonomicnervous system.
神经系统中处理紧张的部分系统为自主神经系统。
It controls bodily functions that we do not consciously control, such as digesting food and pumping blood through the heart.
它能控制人体无意识会控制的一些身体功能，如消化食物和心脏输送血液。
However, the autonomic nervous system is also important in dealing with emotional states.
不过，自主神经系统在处理情绪时非常重要。
When an animal encounters a stressful situation, its autonomic nervous system kicks in to allow it to either fight or run away.
当动物身处紧张环境时，自主神经系统开始发挥作用促使动物选择战或逃。
