The Enteric Nervous System—Your Body’s “Second Brain”?

HOW many brains do you have? If you answer “one,” you are correct. Yet, there are other nervous systems in your body.

大脑呢?如果答案是“一个”,你了。不过科学家说,在体内个“大脑”。

It is the enteric nervous system (ENS). One network of neurons is so extensive that some scientists have referred to it as a “second brain.” 

就是神经系统。这个神经系统复杂完整,因此有些科学家作“第大脑”。

In humans, it is made up of an estimated 200 to 600 million neurons. This complex network of neurons is built into the digestive system.

人体神经系统大约六亿神经元构成,这个复杂网络分布消化系统内。

The sophistication of this chemical operation is mind-boggling. For instance, the intestinal wall is lined with specialized cells that act as chemical detectors, or taste receptors, identifying chemicals present in the food you eat.

人体消化过程复杂精妙,超想象。举例说,肠道内壁排列许多特殊细胞,这些细胞担任味觉感受器角色,就化学探测器一样,能够识别食物化学成分。

This data helps the ENS enlist the right digestive enzymes to break the food down into particles that the body can absorb. Also, the ENS plays a vital role in monitoring the acidity and other chemical properties of food particles and in adjusting the digestive enzymes accordingly.

神经系统根据搜集数据调动消化酶,将食物分解身体能够吸收大小。肠神经系统监测食物颗粒酸度以及其他化学属性,并根据监测结果调节消化酶。 

So the next time you are about to eat a meal, pause and think about all the monitoring, data processing, coordination, and communication that is about to take place in your digestive system!

吃饭之前,不妨下来想想,在消化系统内部即将发生监测、分析、协调、沟通一系列活动,这多么奇妙啊!
