  1. Identify the types of solid joints.
    • Fibrous:
    • 1. Suture
    • 2. Gomphosis
    • 3. Syndesmosis

    • Cartilaginous:
    • 1. Synchondrosis
    • 2. Symphysis
  2. What is the difference between a solid joint & synovial joint?
    • Solid joints:
    • - adjacent surfaces are linked by fibrous connective tissue, or cartilage
    • - restricted movement compared to synovial joints

    • Synovial joints:
    • - connected skeletal components separated by a narrow articular cavity
    • - have a layer of (usually hyaline) cartilage -> covers articulating features
    • - presense of joint capsule (inner synovial membrane & fibrous membrane)
  3. Suture
    adjacent bones are linked by a thin connective tissue layer (sutural ligament)
  4. Gomphosis
    • b/w teeth & adjacent bone
    • ¬†short collagen tissue fibers in the periodontal ligament run b/w tooth root and & bony socket
  5. Syndesmoses
    2 adjacent bones linked by a ligament
  6. Synchondrosis
    2 ossification centers in a developing bone remain sepearated by a layer of cartilage
  7. Symphysis
    • 2 separate bones are interconnected by cartilage
    • Most occur on midline
  8. Explain the characteristics of a typical synovial joint.
    • Articular cartilage
    • Articular (joint) capsule
    • Synovial membrane
  9. Identify the different types of synovial joints.
    • Hinge
    • Condyloid
    • Bicondylr
    • Pivot
    • Saddle
    • Ball-and-Socket
    • Plane
