Joints are the parts that connect the bones and some of them, and when he was detailed to allow one to move during Alazmat greatness linked to its neighbors, so they offer a wide range of motion, kinetic and structural system are three types of joints:
- Fixed joints:
Called "stitching" a link between bony plates that form the skull.
Allow joints fixed the movement is very limited, and the belts thin fibrous tissue connecting one Alazmat one that followed, and examples of this type of arthritis platelets bone of the skull of the baby, which allows the skull lying down to accommodate the growth of brain size, and when fully developed brain fuse the bones of the skull and disappear joints fibrous .
- Cartilaginous joints:
It drives such as "disc" in between paragraphs, and contains a solid sheet-like cartilage viable flexion.
These joint cartilage contain sheets cartilage solid and allow the movement is limited, for example, the detailed iliac coccygeal, where meets greatness iliac (the lower the greatness of the bones of the spine), pelvis, and the discs in between the vertebrae bony spine also promises cartilaginous joints, which are thicker than coccygeal iliac joint and allow greater scope of movement.
- Synovial joints:
It is the most joints ability to move, including the joints of the shoulders, elbows, wrists, fingers and pelvis (hips), knees, ankles and toes, and surrounded by a capsule (portfolio) for fibrous soft-lined membrane articular slippery high, secreted membrane synovial slippery liquid is thick slippery semi-transparent so-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 for the leakage of adjacent bones can slide freely over each other and at the same time prevents them from escaping from each other.
