Structure of synovial joint and muscle attachment

  1. 1. Lloyd Dean Skeletal System
  2. 2. Objectives By the end of the lesson you should be able to: Describe the structure of a synovial joint State the muscle attachments to the skeleton Complete relevant workbook activities on above topics
  3. 3. Structures of a Synovial Joint Ligaments Articular Cartilage Joint Cavity Synovial Membrane Synovial Fluid
  4. 4. Structures of a Synovial Joint Ligaments – Joint bone to bone Articular Cartilage – Covers the ends of bone Joint Cavity – “Hole” filled with synovial fluid Synovial Membrane – Found inside the joint capsule and creates synovial fluid Synovial Fluid – Nourishes joint, removes waste debris and lies in joint cavity How can exercises improve the function of a synovial joint? How would your answer impact your warm up,for example?
  5. 5. Muscle Attachment Muscles need to attach to bones These points are called O_____ & I________ How do we distinguish between each? Origin is the attachment on the bone that does not move Insertion is the attachment on the bone that does move
  6. 6. Muscle Attachment Bone Origin Insertion Femur Humerus Fibula Scapula Tibia Pelvis Sternum Ulna Clavicle Ribs Radius
  7. 7. Bone Origin Insertion Femur Vastus Lateralis and Intermedius Gastrocnemius Iliopsoas Adductor Longus, brevis and magnus Gluteus Medius Humerus Triceps Brachii Deltoid Anterior, Middle & Posterior Latissimus Dorsi Pectoralis Major Supraspinatus Teres MajorFibula Biceps Femoris Solues Scapula Deltoid Anterior, Middle & Posterior Biceps Brachii (Long and Short Head) Supraspinatus Teres Major Trapezius Rhomboids Pectoralise Minor Tibia Tibialis anterior Semitendinosus Pelvis Latissimus Dorsi Internal & External Obliques Transverse Abdominus Sternum Pectoralis Major Ulna Triceps Brachii Clavicle Pectoralis Major Ribs Internal and External Obliques Transverse Abdominus Internal and External Intercostals Pectoralise Minor and Major Internal and External Intercostals
  8. 8. Objectives You should now be able to: Describe the structure of a synovial joint State the muscle attachments to the skeleton Complete relevant workbook activities on above topics
  9. 9. Objectives You should now be able to: Describe the structure of a synovial joint State the muscle attachments to the skeleton Complete relevant workbook activities on above topics
