What joins muscles and bone in several positions available?

The answer is Tendon.

A tendon is a tough, fibrous cord that connects muscles to bones. Tendons are composed of collagen fibers, which are the same type of fibers that make up skin and cartilage. Tendons are strong and flexible, and they allow muscles to pull bones in a variety of directions.

When a muscle contracts, it pulls on its tendon, which in turn pulls on the bone. This action causes the bone to move. Tendons also help to stabilize joints and prevent them from becoming dislocated.

Tendons are essential for movement, and they play an important role in many everyday activities, such as walking, running, and lifting objects.
