Types of Joints and Bursae
Ana Soldo2013/2014Zagreb Medical SchoolMentor: A. Žmegač Horvat
Joint (articulation) A coming together
of two or more bones
Joints
Diarthrosesmovable
Synarthrosesimmovable/ partially movable
Joints
Diarthrosismovable
Synarthrosisimmovable/ partially movable
Diarthrosis (synovial joint) Freely movable
joint
Articular cartilage Joint capsule
fibrous membranesynovial 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 slidingSacroiliac, intercarpal, intertarsal joints
Diarthrosis (synovial joint)
Hinge joint (ginglymus) – allows movement in only one directionInterphalangeal joint, joint between humerus and ulna
Diarthrosis (synovial joint)
Pivot joint – allows rotationProximal and distal radioulnar joint
Diarthrosis (synovial joint)
Saddle joint – allows movement in all directions except rotationFirst carpometacarpal joint
Diarthrosis (synovial joint)
Ellipsoid joint – allows flexion, extension, adduction, abduction, circumductionRadiocarpal joint, metacarpophalangeal joints
Diarthrosis (synovial joint)
Ball and socket joint – largest range of movementHip joint, shoulder joint

Synostosis Syndesmosis Synchondrosis
Synarthrosis
Synostosis Syndesmosis Synchondrosis
Synostosis The joining of two bones - ossification of connecting
tissueHip 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 lifeJoint between first rib and sternum
