Document Summary
Classified as synovial, fibrous, cartiladgenous according to major ct types binding bones together and whether a fluid filled joint capsule is present. Classified based on degree of motion: nonvovable, slightly movable, freely movable. 2 bones united by fibrous ct, no joint cavity, little/no movement. Sutures > seems between bones of skull, some immovable in older adults, opposing bones have interlocking processes (interdigitate). Very stable, tissue between bones is dense regular collagenous ct, periosteum on inner/outer surfaces of adjacent bones continues over the joint. Periosteum + dense fibrous ct = sutural ligament. Fontanel > soft spot, makes skull flexible in new born, allows for growth of head after birth, membranous area in sutures. Synotosis > 2 bones grow together across a joint to form a single bone. Fibrous joint, bones are farther apart than suture joined by ligaments, flexible (some movement can occur). Joints consisting of pegs that fit into sockets, held in place by bundles of regular collagenous ct. ex.
