Did you know?
There are between 640 and 850 muscles in the typical human body, the strongest of which is the masseter muscle in your jaw that is used for chewing food. Muscles make up around 40% of your total body weight. If all of your muscles could pull in one direction at the same time you could create a force of about 25 tons.
Any budding doctor will love this Human Muscle wall sticker, which depicts all of the muscles in the human body in an accurate, full colour drawing. Learn more about how the body works by using this wall sticker to decorate any study, classroom or bedroom.
