Document Summary

A joint is a site where 2 or more bones meet. Structurally 3 types: fibrous, cartilaginous, synovial. Functionally 3 types: synarthroses, amphiarthroses, diarthroses anthro=joint. Bones joined by fibrous ct; no joint cavity so very little to no movement at joint. Seams only found between bones of skull. Overlapping or interlocking of 2 bones; junction filled with very short ct fibers. Cord ligament or sheet of fibrous ct. Peg in socket; only example = tooth in bony socket. Cartilagenous joints: bones are united by cartilage (no joint activity) Epiphyseal plates each of 1st 7 ribs and sternum. Articular surfaces vovered with hyaline cartilage linking plate of fibrocartilage. Articular cartilage: covers opposing bone surfaces cushioning so bone not crushed. Synovial fluid: fills joint cavity; reduces friction. Reinforcing ligaments: restrict movement of joint. Some synovial joints have fatty pads for cushioning (hip/knee joints) or articular discs to improve fit (knee/jaw joints)
