Tendons are tough fibrous bands of tissue that attach bone to bone.
Joints need cartilage to function properly.
The cushioning properties of cartilage are largely due to it being filled with negatively charged chondroitin molecules.
Cartilage lacks water and if water touches cartilage, the cartilage will dissolve.
Bursae are small fluid filled sacs that are not normally found in the body but when present must be treated immediately.
Joints have a large blood supply.
If joints donâ€™t move, they can starve to death.
