2. Articulations and Arthrosis ®

4. Structural Classification of Joints
 based on anatomical characteristics
 presence/absence of space between the two articulating bones
 type of connective tissue that binds the bones together
1. fibrous joints
• no synovial cavity
• fibrous connective tissue rich in collagen fibers
2. cartilaginous joints
• no synovial cavity
• hyaline or fibrocartilage
3. synovial joints
• with synovial cavity
• dense irregular connective tissue with accessory ligaments

6. Functional Classification of Joints
Synarthrosis Amphiarthrosis
Diarthrosis

7. Classification of Joints – structural
and functional characteristics
1. fibrous joints
• suture – unites bones of
skull, synarthrosis
• syndesmoses – greater
distance between
articulating bones, fibrous
connective tissue as a
bundle (ligament) or as a
sheet (interosseus
membrane), amphiarthrosis
• gomphoses – peg and
socket, roots of teeth with
the sockets of the maxillae
and mandible, fibrous

8. Classification of Joints – structural
and functional characteristics
2. cartilaginous joints
 synchondroses –
hyaline cartilage,
ex. epiphyseal
plates, 1st rib and
manubrium,
synarthrosis
 symphyses –
articulating bones
covered with
hyaline but are
connected with a
broad, flat disc of
fibrocartilage, ex.
pubic symphyses,

9. types of synovial joints
3. pivot – rounded/pointed with ring formed by
bone and ligament
• movement: rotation
• atlanto-axial joint, radioulnar

10. Classification of Joints – structural and
functional characteristics
3. synovial joints – reduces friction, absorbs
shock, permits movement (diarthrosis)
structures:
• articular cartilage – hyaline or fibrocartilage
• articular capsule – inner synovial membrane and
outer fibrous capsule
• synovial fluid – hyaluronic acid and interstitial
fluid, for the lubrication and supply of nutrients,
removal of wastes
• accessory ligaments and articular discs –
extracapsular ligaments, intracapsular ligaments

11. types of synovial joints
1. planar – flat or slightly curved surfaces
• movement: side to side, back and forth
• intercarpal, intertarsal, sternoclavicular, acromioclavicular,
sternocostal, vertebrocostal
2. hinge – convex/concave surfaces
• movement: angular, opening and closing
• knee, elbow, ankle, interphalangeal

12. types of synovial joints
4. condyloid/ellipsoidal – convex oval-oval depression
 movement: biaxial (up and down, side to side)
 wrist, metacarpophalangeal
5. saddle – saddle and rider
• movement: side to side, up and down
• carpometacarpal joint (thumb)

13. types of synovial joints
6. ball and socket – ball-like and cup-like
• multiaxial
• shoulder and hip
