Joints are the points of the body where two bones meet. There is often movement between them but sometimes there is not. A joint has two main functions: to allow mobility of the skeletal system<\/a> and to provide a protective enclosure for vital organs.<\/p>\n

How are joints classified?<\/h2>\n

Joints are divided into three categories:<\/p>\n

    \n
  1. \n

    Immovable or Fibrous Joints<\/em><\/h2>\n<\/li>\n<\/ol>\n

    These joints are called \u2018fixed\u2019 or \u2018immovable\u2019 joints because they do not move. They have no joint cavity and are connected via fibrous connective tissue. The skull bones are connected by fibrous joints.<\/p>\n

      Cartilaginous Joints<\/em><\/h2>\n<\/li>\n<\/ol>\n

      These joints also have no joint cavity and the bones are connected tightly to each other with cartilage. These joints only allow a small amount of movement which means that they are called \u2018partly\u2019 or \u2018slightly movable\u2019 joints. The vertebrae are examples of cartilaginous joints.<\/p>\n

        Synovial Joints<\/em><\/h2>\n<\/li>\n<\/ol>\n

        Most of the joints in the body are synovial joints. These joints are \u2018freely movable\u2019 and are characterised by being surrounded by an articular capsule which contains the synovial fluid. This fluid:<\/p>\n
