Human Body - Movement

Text and diagrams that explain the way that musckes contract and relax and produce movement in the joints of the human body.

Human Body - Movement


We can move our bodies into different positions because we have joints.

A joint is a place where two or more bones meet.

Muscles always work in pairs.

To move a joint one of the muscles in the pair contracts (gets shorter) and the other relaxes (gets longer).
