An adherent point is like a sticker that holds something in place. It's a little dot of sticky material that keeps something from moving around or falling off. For example, if you have a toy car and you want to make sure it stays in one spot, you might put an adherent point on the bottom of the car and stick it to a table. That way, the car won't slide around or fall off the table. Adherent points can be really useful when you want to keep things in place, but you don't want to use something too strong or permanent like glue. They're usually pretty easy to remove and won't damage whatever you've stuck them to.
