How does a muscle attach to a tendon and how does a tendon attach to a bone?

Is it physical structures like microscopic hooks/anchors? Some kind of biological "adhesive"?

Edit: Question answered. Several very knowledgeable people have done a great job of explaining that there is no "attachment" rather there is no end between bone/tendon and muscle, they all just merge into each other. Which is pretty amazing when you think about it. Thanks everyone.

Tendons are something in between pure fibrous tissue and bone tissue. So they kinda stick to the respective bone as a very adhesive tissue that is interwoven with the bone cortex. As you follow the tendon to the where it connects with muscle, it is more fibrous is origin and resembles muscle itself in structure. Follow it towards bone, it becomes sturdier and more bone-like in quality.

So tendons are a kind of bridge between mucle and bone where in the outskirts the tissue flows in each other.
