Answer:
Ligament
Step-by-step explanation:
Ligaments hold our bones together and help with movement of joints. For example, think of your knee. Your knee has 4 main ligaments that help you move and help you knee stay together. If you tear one of these ligaments, it is extreamly painful and you often will need surgery to repair said ligament. As you can see, ligaments are very vital to the movement of our bodies.
