Document Summary
Focuses on materials binding bones together and presence/absence of joint cavity. Joint cavity; e. g synovial (only one join cavity) Based on the amount of movement at joint. Bones joined by fibrous connective tissue, no joint cavity present. Mostly synarthrotic (immovable) , and some amphiarthrosis (slightly movable) Slippery fluid in all free spaces in joint capsule, which reduces friction with articulating surfaces. Hyaline cartilage which is smooth and covers opposing bone surfaces, absorbs compression. Tough external fibrous layer; dense connective with periosteum of bone, strengthens joint so bone not pulled apart. Inner synovial membrane layer; makes synovial fluid. , and coers parts of bones not covered by articular cartilage. Associated with synovial joints, not part of join structure. Reduces friction where ligaments, muscles, skin, tendons, or bones rub together. Flattened fibrous sacs lined with synovial membrane. Elongated bursa that wraps around a tendon to reduce friction. Between occipital, condyle and superior articular facet of c1.
