假如你的手指不小心摸到了一个很烫的炉子,会发生什么?情景手指不小心碰到了一个很烫的炉子,立刻发岀“好烫”的信息给脊髓。这时,脊髓会直接发岀指令:“立刻把手指缩回来!”手指接到信息,立即缩回手。想一想,你遇到如此情况的时候,是不是想都不想就把手缩回来了呢?整个过程根本不需要大脑参与。这种潜伏期短、活动形式固定、只需外周传人和脊髓参与的反射活动叫作脊髓反射。模拟脊髓反射脊髓不仅能准确传递信息,还能在身体遇到紧急情况时及时作决定,不需要大脑参与。我们一起来模拟一下脊髓反射的过程。这个活动需要五个人。
If your finger accidentally touches a very hot stove, what happens? Scene finger accidentally ran into a very hot stove, immediately issued a “hot” information to the spinal cord. At this moment, the spinal cord will send a command directly: “Immediately retract your finger! ” Finger to receive information, immediately retracted. Think about it, when you’re in such a situation, do you not want to retract the handle? The entire process does not require brain involvement. This incubation period is short, the form of activity is fixed, and only peripheral afferent and reflex activities involving the spinal cord are called spinal reflexes. Simulating spinal cord reflex spinal cord can not only accurately convey information, but also in the body in case of emergency decisions in a timely manner, without the brain involved. We work together to simulate the process of spinal reflex. This activity requires five people.
