Triorigin classification of a joint structure for a deeper healing of various ailments of joints.Joint-Strucure

Basic Joint Structure

Various bones are connected to each other with the help of Joints. Joints render many types of relative movement to the bones. And according to the type of motion they offer, joints are of numerous types. Despite of existence of many types of joints, their basic construction, more or less remains the same.

The principle elements which unite in construction of joints are: Bones, Cartilage, Synovial membrane and Ligaments.

Bones: Bones are the principle element forming the joint.

Cartilage: The joint ends of the Bones are coated with a thin and elastic layer called cartilage. Its main purpose is to provide a cushioning against every type of shock on the Body. There are many activities which render great amount of shocks to the Body, for e.g. running, playing, Jumping, Fighting etc. The second most important benefit offered by Cartilage is to prevent the Bones to rub against each other, by providing a protective covering to them.

Synovial Membrane: A very delicate connective tissue, lining the capsules of the Joints is called Synovial Membrane. It also provides a covering to Ligaments connected with Caps. Joint oil called Synovia, is secreted from this membrane. This thick and glairy oil helps the smooth functioning of the Joint.

Ligaments: These are generally the bands or bundles of Fibrous tissues, with which the bones are held together. Ligaments are very similar to parallel ATA (PATA) cables, used for connecting storage devices with the motherboard of computers. The fibers are very closely interlaced with each other and present a silvery and shiny aspect.  Ligaments prevent the bones from getting dislocated and provide a controlled movement to the joint. The basic features of Ligament fibers include: their high strength, high flexibility, high toughness and low extensibility  Ligaments are so tough that bone will be broken before any rapture takes place in them.

Besides these elements, there are muscles, which provide a great help in maintain the joint surfaces in proper relation. Another important component in proper functioning of the joints is the pressure of the outside air. That is why, the hip joints are so completely surrounded by the Ligaments that joint becomes completely airtight. Any damage to this protective covering will reduce the air pressure. And this reduced air pressure is very dangerous to the health of bones.

Triorigin classification of joints…


If you want to work on a joint part specifically then better enter the joint via structure i.e reach the particular limb and rent NO you reach joints of that limb for ex.To reach  Knee joint of right leg  formula is like this HO is body NE is structure HE is hetero model NE is extremeties HO is right leg NO is joints of right leg HE is knee joint which is most active of all joints.

Now structure of a joint

HE is covering layers i.e is  capsule of joint.In capsule fibrous outer part is HE, inner synovial membrane is HO.

HO is bony tissue in which HE is intraarticular cartilage and HO is bones body  OR cartilage can be considered as skin of bone i.e HE in HO.

Ligaments are NE.

NO of a joint should have 4 parts… HE is Bursae i.e many space packets,HO is central joint space,NE is synovial fluid,NO is communicating system of which HE is artery HO is vein NE is lymphatics NO is nerves.



BURSAe in joints….

Bursae are thin, lubricated cushions located at points of friction between a bone and the surrounding soft tissue, such as skin, muscles, ligaments and tendons. A bursa lies between a bone and opposing surface (e.g. skin) like a tiny water balloon with only a few drops of fluid in it, wedged between two surfaces.

Key characteristics of bursae include:

  • A healthy bursa is thin. For example, a research study of a relatively large bursa located between the kneecap and skin showed the average bursa measurement to be about four centimeters in diameter and just a few millimeters thick.1
  • Bursae vary in size depending on the individual and location in the body.
  • Some bursae are just beneath the skin™s surface while others are deep below muscles and other soft tissue.
  • An adult body contains about 160 bursae.
  • Some bursae are present at birth and others develop later as the result of frequent friction. For example, most people develop a bursa in the elbow called the olecranon bursa sometime after age 7.2
  • Other bursae may develop depending on the individual. For example, a person who regularly wears constricting shoes or has abnormal foot anatomy may develop a bursa on the outside of the big toe joint.
