What are the international joints?
also known as the intermediate articulation, the intermediate joints are the joints between the carpal bones of the hand. This collection of eight irregularly shaped bones, located just behind the radiocarpal or wrist, helps to transmit strength through the joint of the wrist and to the hand, allowing complex movements of the hands. Intermediate joints are classified as arthrodial or planes, joints that allow bones to slide around another in different directions. In carpus, these joints allow simultaneous bone movements in relation to each other during grip, stretching and other hands. These firmly packed bones in the shape of a rock shape include scaphoid, lunate, triquetrum, pisiform, trapezoid, trapezoid, capital and hamina. They are roughly arranged in two lines, the nearest wrist is referred to as the proximal series and the closest metacarpals in hand referred to as the distal line. In the proximal series, the bones of Scaphid, Lunate, Triquetrum and Pisiform are, while the remaining four are found in the distal series.
intermediate joints include joints between the bones of the proximal series, those between the bones of the distal series and between two rows. These joints are largely covered with short, strong ligaments made of dense collagen fibers that hold the bones together. In each row there are dorsal, vollar and interosseous ligaments: those who connect the bones on their dorsal or rear surfaces, those that connect the bones on their palm surfaces and those between the neighboring surfaces of the bone. Between two rows there are midcarpal ligaments that are perpendicular in the direction of ligaments found in two rows. All intermediate bones hold Carpuser so that it can function as a unit and transmission forces through the bones between the wrist and hands.
Between Kostimi Karpus and internal intermediate joints is the synovial membrane. Most of the moving joints of the body contain synovial capsules with a membrane between neighboring bones. There is a liquid in this capsule thatIt lubricates bones against each other and some form of cartilage that acts as a pillow. In two-cone joints, such as the elbow and knee, the synovial capsules are relatively simple, contained and a shape similar to the bag.
On the other hand, the synovial membrane is more complex and strangely shaped. It runs linearly between two lines, as well as forms, spikes that extend between the bones of both rows. The membrane of the intermediate joints protects the joint cavity, releases the lubricating synovial fluid to reduce the inflammation between the bones during the movements of the hands, and provides the buffer that keeps the bones to make direct contact between themselves.
