Document Summary
Movable joints, vertebral column , must provide a combination of support and flexibility. Immovable joints btw the cranial bones afford the best possible protection for the brain and sense organs. Are classified according to the manner in which the adjacent bones are bound to each other , which corresponding differences in how freely the bones can move . Or synarthorsis , synarthrodial joint : adjacent bones are bound by collagen fibers that emerge from the matrix of the bone, cross the space between them , and penetrate into the matrix of the other. Sutures, gomphoses and syndesmoses in both suture and gomphose the fibers are very short and allow for little movement. Syndesmoses-the fibers are longer and the attached bones are more moveable. Are immovable fibrous joints, closely bind the bones of the skull. Serrate sutures : wavy lines along which the adjoining bones firmly interlock with each other by their serrated margins , like pieces of jigsaw puzzle.
