And these are the joints that connect our bones and hold those bones very strongly, very tightly. And so these fibrous joints basically allow no movement between the bone and these fibers. Joints are found in the skull as well as around our teeth. So when our human is born, the skull actually consists of individual bones. But as the organism develops, as the human develops, these bones basically fuse together. And the regions where they fuse, that is known as a suture.
