Diarthrotic Joints

  1. 1. Diarthroti c Joints Estorco, Clar Llave, Krystalyn Perez, Reiss Ramirez, Ian
  2. 2. Classification of Joints• (1) Fibrous joints • These joints are also known as: • Dense connective tissues • Synarthrotic joints connect bones • Considered immovable • Between bones in close contact • Amphiarthrotic joints • Slightly movable• (2) Cartilaginous joints • Diarthrotic joints • Hyaline cartilage or fibrocartilage • Freely movable connect bones• (3) Synovial joints • Most complex • Allow free movement 2
  3. 3. (diarthrosis)- freely moveable pelvis ligaments femur
  4. 4. hyalinecartilage synovial cavity femur
  5. 5. Shoulder joint •Ligaments prevent displacement • Very wide range of movement (circumduction)
  6. 6. Elbow joint•Flexion and extension• Many reinforcingligaments• Stable joint
  7. 7. The Hip Joint• Many reinforcing ligaments• Less freedom of movement than shoulder joint• Circumduction
  8. 8. The Knee Joint• Femur articulates anteriorly with patella• Strengthened by many ligaments and tendons
  9. 9. • Complex Joint• Articular disc• Gliding above disc• Hinge below disc• Movements: - depression - elevation - protraction - retraction
  10. 10. • Planar Joint• Hinge Joint• Pivot Joint• Saddle Joint• Ball & Socket Joint• Condyloid or Ellipsoid Joint
  11. 11. • Convex surface of bone fits in concave surface of 2nd bone• Unixlateral like a door hinge• Examples: - Knee, elbow, ankle, interphalangeal joints• Movements produced: - flexion - extension - hyperextension
  12. 12. • Bone surfaces are slightly curved• Side to side movement only• Rotation prevented by ligaments• Examples: - intercarpal to intertarsal joints - sternoclavicular joint - vertebrocostal joints
  13. 13. • Rounded surface of bone articulates with the ring formed by the 2nd bone & ligament• Monoaxial since it only allows rotation around longitudinal axis• Examples: - proximal radioulnar joint - supination - pronation - atlanto-axial joint - Turning head side to side “no”
  14. 14. • One bone saddle-shaped, other bone fits like a person riding on the saddle• Biaxial - circumduction allows the tip of the thumb to travel in a circle - Opposition allows thumb to touch tip of other fingers• Examples: - Trapezium of carpus and metacarple of thumb
  15. 15. • Ball fitting into a cup-like depression• Multiaxial - flexion/extension - abduction/adduction - rotation• Examples: - shoulder joint - hip joint
  16. 16. • Oval-shaped depression fits into oval depression• Biaxial= flex/extend or adduct/abduct is possible• Examples: - Wrist and metacarpophelangeal joints for 2 to 5 digits
  17. 17. Figure 8.5a Movements allowed by synovialjoints. Gliding (a) Gliding movements at the wrist
  18. 18. Figure 8.5b Movements allowed by synovialjoints. Hyperextension Extension Flexion (b) Angular movements: flexion, extension, and hyperextension of the neck
  19. 19. Figure 8.5e Movements allowed by synovial joints. Abduction Adduction Circumduction(e) Angular movements: abduction, adduction, and circumduction of the upper limb at the shoulder
  20. 20. Figure 8.5f Movements allowed by synovial joints. Rotation Lateral rotation Medial rotation(f) Rotation of the head, neck, and lower limb
  21. 21. Figure 8.6a Special body movements. Pronation Supination (radius (radius and rotates ulna are over ulna) parallel) (a) Pronation (P) and supination (S)
  22. 22. Figure 8.6b Special body movements. Dorsiflexion Plantar flexion (b) Dorsiflexion and plantar flexion
  23. 23. Figure 8.6c Special body movements. Inversion Eversion (c) Inversion and eversion
  24. 24. Figure 8.6d Special body movements. Protraction Retraction of mandible of mandible(d) Protraction and retraction
  25. 25. Figure 8.6e Special body movements. Elevation Depression of mandible of mandible(e) Elevation and depression
  26. 26. Figure 8.6f Special body movements. Opposition (f) Opposition
  27. 27. Type of joint movement:• Flexion- bent knee• Extension- extend knee• Hyperextension- bring leg back• Dorsi flexion- heal• Plantar flexion- toe• Abduction- leg out• Adduction-leg in• Rotation- twisting• Circumduction- circular motion• Supination- palm up• Pronation- palm down• Eversion- foot out• Inversion- foot in• Protraction- chin forward• Retraction- chin back• Elevation- shoulders up• Depression- shoulders down
