有大神帮忙看看这篇文章大概讲了什么
Now you are sitting in a garden reading a book.As the sun goes in and the breeze begins to blow,your skin gets cooler.The nerves which end in the skin notice this,and they send little electrical message about it.These are rather like telegraph messages.
The messages (they are called nerve impulses)go from the skin,along the nerves to the spinal cord (脊髓).From there they pass up the spinal cord to the brain.When they arrive at the brain you have the feeling of being cold.Of course,the message travels very,very quickly from the skin to the brain.
In your brain the never message cause some very complicated things to happen.They cause you to think.You think how cold you are and how you can get warm again.You decide that the best thing to do is to put your coat on.As soon as you decide to put your coat on,more nerve messages begin.This time they go in the other direction.They start in the brain,go down the spinal cord,and then out along the nerves.Instead of going to the skin,however,these messages go to muscles.When they arrive there,the muscles grow shorter-they contract.It is these contractions which make your body move in the right way to put your coat on again.

现在你坐在花园里读一本书.当太阳和风开始吹,你的皮肤变的凉爽.在皮肤里面的神经感受到这些,他们发出小电流信息.这更像是一份电报.
信息（他们被称为神经冲动）从皮肤,沿神经到脊髓（脊髓）.他们从那里经过从脊髓到大脑.当他们到达大脑,你的感觉是凉爽的.当然,这些信息很快从皮肤传到大脑.
你的大脑神经信息会引起一些很复杂的事情.他们让你思考.你觉得冷并且知道如何能得到温暖.你认为最好的办法是穿上你的外套.一旦你决定要穿上你的外套,更多的神经信息开始活动.这一次他们朝另一个方向去.他们开始在大脑中,沿着脊髓,然后沿神经.相反的是,这些信息传动肌肉而不是皮肤.当他们到了那里,肌肉收缩.正是这些收缩,使你的身体做出正确的决定穿上衣服.

讲述了人的神经系统在天气寒冷的时候从皮肤表层将需要温暖的信息传输到脊髓再到大脑，由大脑传输回脊髓再支配全身的肌肉来配合穿衣的动作。
简单讲就是人的神经系统在寒冷气温下是如何配合大脑来支配人体活动的。
