BBC环球慢速英语 第385期:触觉(6)

voice 2: The human touch is a powerful sense. Someone puts their arm around you when you are sad. No one speaks. But somehow you feel better. When you are young, you hold your mother's hand when you are afraid.
声音2：人类的碰触具有强大的意义。当你难过时，会有人伸出手抱住你。没有人说话。但是不知为什么，你就是会感觉好受些。你小时候，在害怕时会握住你妈妈的手。

voice 1: The sense of touch is different to the other four senses - seeing, hearing, smelling and tasting. These senses are in particular parts of the body. But the sense of touch is all over the body. It is in the skin. It originates in the deepest part of skin - the dermis. The dermis is filled with very small nerve endings. These react to touch. They carry information to the spinal cord that goes through the backbone. The spinal cord sends messages to the brain.
声音1：触觉与视觉、听觉、嗅觉和味觉这四种感觉官能不同。这些感觉官能都是身体特定部位的感知。但是触觉是全身的感知。触觉是皮肤的感觉。触觉是源于皮肤最深层真皮层的感觉。真皮层布满了极小的神经末梢。这些神经末梢对触碰做出反应。它们将信息传递给穿过脊柱的脊髓。脊髓再将这些信息传递给大脑。
