a lot of Dense fibrous CT
sutures - found only in skull, eventually occifies
syndesmoses - ligaments , example is in between the radius and ulna - interosseous membrane
gomphoses - found only in mouth , peg in socket type of joint
synovial - freely movable
most common
articular cartilage protects ends of bones, joint cavity containing the lubricant synovial fluid (hyaluronic acid )
cartilaginous joint - range of mobilities
bones connected by cartilages, lack joint cavities
synchondroses
contains hyaline cartilage, eg. epiphyseal plate in children also first rib between the costal cartilage and the manubrium of the sternum
sympheses
compressable, shock absorbers
function - extent of function
synathroses - immovable
amphiarthroses - slightly immovable
diarthroses - freely movable
muscle contraction
immovable is origin, movable is insertion
