Do you know how detailed works? How do joints work? What types of arthritis?

Joints are linking parts of the bones and some of them, and detailed what was allowed to one of Alazmat move during its neighboring linked to greatness, they do provide a wide range of motion, and structural kinetic device are three types of joints:


- Arthritis fixed:


Called the "seam", which connects between the plates that form the skull bone.
Allows joints fixed movement is very limited, and the belts high of fibrous tissue linking one Alazmat one that followed, and examples of this type of arthritis platelets bone of a skull baby, which allow the skull بالتمدد to accommodate the growth in the size of the brain, and when fully developed brain fuse bones of the skull and disappear joints fibrous .


- Joints Acartilaginous:


It is such as CD "disc" located between the vertebrae, and contain a solid sheet-like cartilage removable flexion.
These joints cartilage containing sheets chondrocytes solid and allow the movement is limited, for example, detailed iliac sacrococcygeum, where you meet greatness iliac (which is the lowest the grandeur of the bones of the spine), pelvis, and the discs in between the vertebrae bony spine also states longer joints of chondrocytes, which are thicker than iliac joint sacrococcygeum and allow greater field of motion.


- Synovial arthritis:


It is more joints capable of movement, including the joints, shoulders, elbows, wrists and fingers and pelvis (hips), knees, ankles and toes, surrounded by a capsule (portfolio) fibrous soft-lined membrane articular slippery high, and secreted membrane synovial slippery liquid is thick slippery semitransparent called synovial fluid which is which allows friction-free movement, and synovial fluid also helps to protect the joints because it works as a contraceptive can leak adjacent bone from sliding freely on top of each other and at the same time prevents them from degeneration of each other.
