The role of bones
The role of bones is to give your body shape, hold the body up and to protect vital organs such as the heart. They also store essential minerals such as calcium, phosphorus & bone marrow. This is necessary to our survival as bone marrow is where new blood cells are made.
There are 5 different shapes of bones within the body: long (the upper arm), short (the hand), flat (the ribs), irregular (the vertebrae) and sesamoid (the kneecap). These all play different roles within the musculoskeletal system and grow throughout your lifetime until you reach a fully grown adult.
The role of joints
Joints are where two or more bones come into contact with each other. They contain cartilage which works to cushion the joints to stop them rubbing together and causing painful damage, as well as connecting one bone to the other. Joints also contain ligaments which join bones to each other in order to strengthen.
There are different types of joints within the body that have different uses. Firstly, you have synovial joints which contain synovial fluid. These are found in the arms and legs, the fluid helps the bones to move over each other so you can move easily. You then have cartilaginous joints in the spine and pelvis which are more stable but you cannot move as much. You also have fibrous joints that are just to stabilise and you cannot move them. These can be found in areas such as the skull.
Why is it important to look after your bones and joints?
As you now know the roles of the bones and joints, you can see why it is so important to keep them healthy. Damage to the bones can lead to a lot of pain and mean you can’t use that part of your body; if you’ve ever broken your arm, you’ll know how painful it is and how long your arm has to be in a cast for! A breakage or fracture to your bones due to injury can be fixed over time, however, general wear and tear leading to weakness can cause more long-term issues. Bone loss could eventually lead to low bone density (osteopenia) where the bones are weak. This could then lead to osteoporosis where the bones become porous. As a result of this, they are more likely to break so you’re more at risk from a simple fall.
For your joints, they can begin to deteriorate over time and this can lead to pain that limits movement. A lack of synovial fluid can also lead to the bones rubbing together causing a great deal of pain and discomfort. If you don’t look after your joints, this could also lead to pulled ligaments, which is most common for athletes. If your joints get to a certain point of disrepair, you could end up with different forms of arthritis, where the joints have gone past a point of no return so you can only cope with the symptoms instead of fixing the damage. This is why it is important to always take care of your joints to keep them healthy and moving freely before it is too late.
