A joint is where two or more bones meet, such as in the fingers, knees, and shoulders. Joints hold bones in place and allow them to move freely within limits. Most of the joints in our body are surrounded by a strong capsule. The capsule is filled with a thick fluid that helps to lubricate the joint. These capsules hold our bones in place. They do this with the help of ligaments. These are a bit like very strong elastic bands. The ends of the bones within a joint are lined with cartilage. This is a smooth but tough layer of tissue that allows bones to glide over one another as you move. If we want to move a bone, our brain gives a signal to the muscle, which then pulls a tendon, and this is attached to the bone. Muscles therefore have an important role in supporting a joint.
