Weismann barrier

Weismann barrier is like a wall between two parts of your body. It helps to keep some of the cells in your body separate from the other cells so that your body can work properly. For example, it helps to keep the cells in your nervous system separate from the cells in the rest of your body. This way, the cells in your nervous system can send signals to different parts of your body, but they are protected from other cells so they don't get too mixed up.
