Document Summary

Functionally: synarthroses - suture, immovable, amphiarthroses - middle, small movements possible, diarthroses - fully movable. = synostose, no movement: seams only found between bones of skull, attaching bones rmly, overlapping or interlocking of 2 bones; junction lled with very short ct bers. Syndesmoses: limited movement, short cord (ligament) or sheet (interosseous membrane) of brous ct. Gomphoses: peg-in-socket; only example = tooth in bony socket, anchored. Synchondroses: areas of growth: eg: epiphyseal plates, between each of 1st 7 ribs & sternum. Symphysis: articular surfaces covered with hyaline cartilage - linking plate of brocartilage, strength with exibility: eg: pubic symphysis, intervertebral joints. 5 characteristics: articular cartilage covers opposing bone surfaces cushioning so bone not crushed, joint cavity. = synovial cavity; uid- lled: articular capsule double-layered, synovial uid. Inner synovial- source of the uid: reinforcing ligaments restrict movement of joint. Plane joints: 2 at opposing surfaces, gliding movements, e. g. intercarpal joints (wrist, some of ankle, vertebrae)
