Document Summary

Joints are sites where two or more bones meet; give mobility and hold skeleton together. Structure what holds the bones together and whether or not there is a cavity; fibrous, cartilaginous, and synovial: fibrous joints bones are joined by dense fibrous connect tissue, no cavity very little movement. Sutures: bones of skull that are joined by very short ct fibers overlap the 2 bones making a seam;\ immovable, otherwise it would damage brain. Syndesmoses: bones connected by ligaments, cords or band of fibrous ct (interosseous membrane: allow very limited movement - short (i. e tibia and fibula) allow little movement, longer (i. e radius and ulna) allow more movement. Gomphoses: peg-in-socket, only tooth in bony alveolar socket ct is short periodontal ligament: cartilaginous united by cartilage, no cavity. Synchondroses: bar of hyaline cartilage uniting bones at synchondrosis i. e epiphyseal plates in long bones of children (area of growth), immovable joint btwn costal cartilage of rib 1 and manubrium, and sternum.
