Joint (articulation) ? A coming together of two or more bones
Joints Diarthroses movable Synarthroses immovable/ partially movable
Joints Diarthrosis movable Synarthrosis immovable/ partially movable
Diarthrosis (synovial joint) ? ? ? Freely movable joint Articular cartilage Joint capsule fibrous membrane synovial membrane ? Joint cavity
Diarthrosis (synovial joint) ? Additional components: • Ligaments • Fat pads • Disci/Menisci • Bursae
Diarthrosis (synovial joint) ? Additional components: Ligaments – add strength to the joint capsule or limit movements
Diarthrosis (synovial joint) ? Additional components: Fat pads - help to protect joints from mechanical damage
Diarthrosis (synovial joint) ? Additional components: Discus/Meniscus – fibrous cartilage within a joint, increases compatibility
Diarthrosis (synovial joint) ? Additional components: Bursa – closed sac of synovial fluid, usually found beetween bones and tendons or muscles around a joint, helps to reduce friction
Diarthrosis (synovial joint)
Diarthrosis (synovial joint)
Diarthrosis (synovial joint) ? Plane joint – permits sliding Sacroiliac, intercarpal, intertarsal joints
Diarthrosis (synovial joint) ? Hinge joint (ginglymus) – allows movement in only one direction Interphalangeal joint, joint between humerus and ulna
Diarthrosis (synovial joint) ? Pivot joint – allows rotation Proximal and distal radioulnar joint
Diarthrosis (synovial joint) ? Saddle joint – allows movement in all directions except rotation First carpometacarpal joint
Diarthrosis (synovial joint) ? Ellipsoid joint – allows flexion, extension, adduction, abduction, circumduction Radiocarpal joint, metacarpophalangeal joints
Diarthrosis (synovial joint) ? Ball and socket joint – largest range of movement Hip joint, shoulder joint
Joints Diarthroses movable Synarthroses immovable/ partially movable
Synarthrosis Synostosis Syndesmosis Synchondrosis
Synarthrosis Synostosis Syndesmosis Synchondrosis
Synostosis ? The joining of two bones - ossification of connecting tissue Hip bone
Synarthrosis Synostosis Syndesmosis Synchondrosis
Syndesmosis ? ? Slightly movable joint Bony surfaces united by connective tissue Suture Interosseous membrane Gomphosis
Synarthrosis Synostosis Syndesmosis Synchondrosis
Synchondrosis ? ? Cartilaginous union Mostly at younger age, during life cartilage replaced by bone, small number remain for life Joint between first rib and sternum
