The skeleton of an adult human being has approximately 206 bones, not counting the teeth, the sutural or wormian bones (supernumerary of the skull) and the sesamoid bones. The human skeleton participates (in a person with a normal weight) with around 12 % of the total body weight. Therefore, a person who weighs 75 kilograms, 9 kilograms of them are for his skeleton.

 

A muscle is a soft tissue found in most animals. They generate movement when contracting or extending when relaxing. In the human body (and in all vertebrates) the muscles are attached to the skeleton by means of tendons, thus being responsible for the execution of body movement.
