1 Types of Joints and Bursae Ana Soldo 2013/2014 Zagreb Medical School Mentor: A. Žmegač Horvat

2 Joint (articulation)  A coming together of two or more bones

3 Joints Diarthroses movable Synarthroses immovable/ partially movable

4 Joints Diarthrosis movable Synarthrosis immovable/ partially movable

5 Diarthrosis (synovial joint)  Freely movable joint  Articular cartilage  Joint capsule fibrous membrane synovial membrane  Joint cavity

6 Diarthrosis (synovial joint)  Additional components: Ligaments Fat pads Disci/Menisci Bursae

7 Diarthrosis (synovial joint)  Additional components: Ligaments – add strength to the joint capsule or limit movements

8 Diarthrosis (synovial joint)  Additional components: Fat pads - help to protect joints from mechanical damage

9 Diarthrosis (synovial joint)  Additional components: Discus/Meniscus – fibrous cartilage within a joint, increases compatibility

10 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

11 Diarthrosis (synovial joint)

12

13  Plane joint – permits sliding Sacroiliac, intercarpal, intertarsal joints

14 Diarthrosis (synovial joint)  Hinge joint (ginglymus) – allows movement in only one direction Interphalangeal joint, joint between humerus and ulna

15 Diarthrosis (synovial joint)  Pivot joint – allows rotation Proximal and distal radioulnar joint

16 Diarthrosis (synovial joint)  Saddle joint – allows movement in all directions except rotation First carpometacarpal joint

17 Diarthrosis (synovial joint)  Ellipsoid joint – allows flexion, extension, adduction, abduction, circumduction Radiocarpal joint, metacarpophalangeal joints

18 Diarthrosis (synovial joint)  Ball and socket joint – largest range of movement Hip joint, shoulder joint

19 Joints Diarthroses movable Synarthroses immovable/ partially movable

20 Synarthrosis SynostosisSyndesmosisSynchondrosis

21 Synarthrosis SynostosisSyndesmosisSynchondrosis

22 Synostosis  The joining of two bones - ossification of connecting tissue Hip bone

23 Synarthrosis SynostosisSyndesmosisSynchondrosis

24 Syndesmosis  Slightly movable joint  Bony surfaces united by connective tissue Suture Interosseous membraneGomphosis

25 Synarthrosis SynostosisSyndesmosisSynchondrosis

26  Cartilaginous union  Mostly at younger age, during life cartilage replaced by bone, small number remain for life Joint between first rib and sternum

27  Sustav organa za pokretanje, Werner Platzer  http://hr.wikipedia.org/wiki/Zglob  www.merriam-webster.com

 Where two bones interconnect  400 + joints  Approximately 230 movable and semi-movable joints  The structure of a joint determines the type and amount.
