1 Joints of the Human Body ASA Bio 2014 Williams

2 Joints Where 2 (or more) bones come together Allows movement Represent the weakest part of the skeleton

3 Types of Joints 3 types of joints o Immovable (Synarthrosis) o Slightly movable (amphiarthrosis) o Fully movable (diarthrosis)

4 Immovable (Synarthrosis) No movement between bones “Fibrous” joints o Sutures

5 Immovable (Synarthrosis) No movement between bones “Fibrous” joints o Sutures o Syndesmosis

6 Immovable (Synarthrosis) No movement between bones “Fibrous” Joints o Sutures o Syndesmosis o Gomphosis

7 Slightly Movable (Amphiarthrosis) Very slight movement “Cartilaginous” joints o Synchondrosis

8 Slightly Movable (Amphiarthrosis) Very slight movement “Cartilaginous” joints o Synchondrosis o Symphysis

9 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal)

10 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal) o Hinge joint (ginglymus)

11 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal) o Hinge joint (ginglymus) o Pivot joint (trochoid)

12 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal) o Hinge joint (ginglymus) o Pivot joint (trochoid) o Condyloid (ellipsoid)

13 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal) o Hinge joint (ginglymus) o Pivot joint (trochoid) o Condyloid (ellipsoid) o Saddle joint (sellar)

14 Fully Movable (Diarthrosis) Greatest degree of flexibility “Synovial” joints o Plane joint (arthroidal) o Hinge joint (ginglymus) o Pivot joint (trochoid) o Condyloid (ellipsoid) o Saddle joint (sellar) o Ball & socket (spheroidal)

15 “Synovial” Joints Articular capsule o Cartilage (hyaline) o Fibrous joint capsule o Synovial membrane o Synovial fluid

16 Joints Ligaments: fibrous band that connects two bones o Limits the range of motion at the joint

17 Joints Ligaments: fibrous band that connects two bones o Limits the range of motion at the joint Cartilage: connective tissue that surrounds the ends of bones o Protects bones from wearing down

18 Joints of the Body Plane joint o Wrist (inter-carpal), Ankle (inter-tarsal), Patella

19 Joints of the Body Hinge joint o Elbow (humerus/ulna), Knee (femur/tibia), Fingers & Toes (inter-phalangeal), Jaw (temporomandibular)

20 Joints of the Body Pivot joint o Forearm (elbow/radius/ulna), Neck (atlanto-axial)

21 Joints of the Body Condyloid joint o Knuckles (metacarpal-phalangeal), Neck (atlanto- occipital)

22 Joints of the Body Saddle joint o Thumb

23 Joints of the Body Ball & socket joint o Shoulder (gleno-humeral), Hip (ilio-femoral)

24 Joints of the Body Plane joint o Wrist (inter-carpal), Ankle (inter-tarsal), Patella Hinge joint o Elbow (humerus/ulna), Knee (femur/tibia), Fingers & Toes (inter-phalangeal), Jaw (temporomandibular) Pivot joint o Forearm (elbow/radius/ulna), Neck (atlanto-axial) Condyloid joint o Knuckles (metacarpal-phalangeal), Neck (atlanto- occipital) Saddle joint o Thumb Ball & socket joint o Shoulder (gleno-humeral), Hip (ilio-femoral)
