How do Muscles and Joints work together?

Our Home- schooled students aged 11-12, have been learning all about the muscles and joints in the human body! Muscles move body parts by contracting and then relaxing. Muscles can pull bones, but they can’t push them back to the original position. So they work in pairs of flexors and extensors. The flexor contracts to bend a limb at a joint. A joint is the part of the body where two or more bones meet to allow movement. Generally speaking, the greater the range of movement, the higher the risk of injury because the strength of the joint is reduced. The students have done various exercises and have investigated what happens when they tense their muscles by using the muscle ‘scrunch and relax’ method. They can now successfully label different muscles and joints within the human body!
