Presentation Transcript

  1. Joints • Exam #1: Thursday April 12th • 1:30-2:50 in Hogness Auditorium • bring scantron • review session Monday at 5:30 in • T-435 HSB • 1 handout for today

  2. Name this cell. List one of it’s functions. Name this space. What is in this space? John broke his ulna, does he need crutches? The mandible articulates with the ___________ bone.

  3. Joints • Different type of joints • fibrous • cartilaginous • synovial • anatomy • stabilizers • temporomandibular joint • anatomy • TMJ syndrome • shoulder joint • anatomy • common injuries • knee joint • anatomy • common injuries

  4. Joint classification • manner or type of material by which bones articulate • relates to movement Fibrous or cartilaginous synovial

  5. Fibrous • bound by collagen • fibers • little or no movement • Cartilaginous • linked by cartilage • some movement

  6. Examples of fibrous joints in the skull

  7. Cartilaginous Joints • linked by cartilage • hyaline or fibrocartilage Rib 1 vs 2-12

  8. Synovial joints • freely moveable • articulating bones covered with • hyaline cartilage • bones separated by joint cavity • joint cavity contains synovial fluid • joint is enclosed by joint capsule

  9. Parts of a synovial joint Ligaments Articular (hyaline) cartilage Joint (articular) capsule (Synovial membrane + fibrous capsule) Joint cavity (contains synovial fluid) Synovial fluid and warming up

  10. Bursa • sac filled with synovial fluid • between muscles or tendons • and bones • for protection and sliding • bursitis - inflammation • Tendon Sheaths • elongated bursae • wrap around a tendon • for protection and sliding • tenosynovitis • tendonitis

  11. How do you stabilize a synovial joint? Name & how (4 ways)

  12. Fig. 9.6(TE Art) Ball-and-socket joint (humeroscapular) Pivot joint (radioulnar) Hinge joint (humeroulnar) Gliding joint (intercarpal) Saddle joint (trapeziometacarpal) Condyloid joint (metacarpophalangeal)

  13. Temporomandibular joint (TMJ) Mandibular fossa • Depress & elevate • Medial & lateral excursion • Protraction & retraction

  14. TMJ dislocation

  15. Masseter Temporomandibular ligament Temporalis TMJ syndrome

  16. Ball and Socket joints Coxal joint Humeroscapular joint

  17. Humeroscapular joint (Glenohumeral) • articulating bones? • flex & extend • hyperextend • abduct & adduct • medial & lateral rotation • circumduction What about protraction & retraction of the scapula?

  18. Sternoclavicular joint • Scapular anatomy • acromion • spine • coracoid process • glenoid cavity • AC joint

  19. Acromioclavicular (AC) joint Acromion Supraspinatus Subdeltoid bursa deltoid Glenoid cavity Glenoid labrum

  20. Subacromial bursa Coracohumeral Glenohumeral ligaments Transverse humeral Biceps tendon

  21. Posterior view Anterior view supraspinatus infraspinatus Teres minor subscapularis Rotator cuff muscles

  22. Supraspinatus tendon Infraspinatus tendon Glenohumeral ligament glenoid labrum Subscapularis tendon Teres minor tendon Glenohumeral ligaments Lateral view of glenoid fossa

  23. Shoulder separation – Acromioclavicular joint

  24. 1. What is this? Function? 2. What is this? Function? 3. What is this? Function? 4. When the head of the humerus comes out of the glenoid fossa, what is that injury called?

  25. Tibiofemoral joint (knee) • articulating bones • tibia – femur • (patellofemoral joint) • movements- modified hinge • flex • extend • rotation when flexed • “locking” when fully • extended

  26. Medial meniscus Lateral meniscus Knee flexed Menisci = Fibrocartilage pads

  27. Quadriceps tendon Prepatellar bursa Joint capsule Synovial membrane Meniscus Patellar ligament

  28. quads quads patella Prepatellar bursa patella ? Synovial Capsule

  29. Housemaid’s knee (from a wrestling website….) aka prepatellar bursitis

  30. Intracapsular & extracapsular ligaments of knee Lateral (fibular) collateral lig. Ant. Cruciate lig. Post. Cruciate lig. meniscus Medial (tibial) collateral ligament Posterior Anterior

  31. hyperflexion hyperextension

  32. Deviations of the tibia from the midline • unequal weight distribution • unequal wear & tear • abnormal patella tracking = chondromalacia

  33. before after

  34. Osteoarthritis (OA) Rheumatoid arthritis (RA)

  35. Exam #1 this Thursday here in Hogness Bring a scantron Be on time! Muscle tissue will NOT be on exam #1
