In addition to this, the heart and lungs areprotected by our 12 pairs of ribs.    A joint is where two bones fit into anotherbone which is rounded, the rounded shape holds the bone to be held securelywhich enables movement.

Muscles are attached to our bones by something called atendon, a tendon is made up of strong fibrous tissue. Similar to a tendon amuscle is a bundle of strong fibrous tissues. Muscles give our body powerfulbody strength e.g power to run.   Theout-side layer of our bone is a thin closely compacted substance that holds ourblood and nerve vessels that supplies our bone with the right nourishment togrow and maintain health this layer is called the Periosteum.
