Document Summary
Joint (articulation): any point where two bones meet. Arthrology: science of joint structure, function and dysfunction. Biomechanics: movements and mechanical processes in body, including the physics of blood circulation, respiration and hearing. Kinesiology: the study of musculoskeletal movement (branch of biomechanics) Immobile joint formed when the gap between two bones ossifies and becomes a single bone. Adjacent bones are bound by collagen fibers that emerge from one bone, cross space and penetrate the other. a. Closely bind the bones of the skill together. Serrate sutures: wavy lines where bones firmly interlock. Lap (squamous) sutures: overlapping, beveled edges between two bones. Plane (butt) sutures: straight non-overlapping edges between two bones. Two bones are bound by relatively long collagenous fibers. More mobility because of the length of fibers/distance between bones. Cartilaginous joints (amphiarthosis or amphiarthodial joint) a. b. Surfaces between the bones are covered in articular cartilage. Nourishes the articular cartilage, removes their wastes and makes movements at synovial joints friction free.
