  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 • Immovable (Synarthrosis) • Slightly movable (amphiarthrosis) • Fully movable (diarthrosis)

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  22. Joints of the Body • Saddle joint • Thumb

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

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