Joints

• Articulation is any place where a bone meets another bone/cartilage
• Anatomy of joint determine stability and mobility

  • more mobility, less stability
  • more stability, less mobility
• Function classification of joints

  • Synarthrosis = immobile joint
  • Amphiarthrosis = joint with limited mobility
  • diathrosis = freely moveable joint
• Structural classification of joints

  • Fibrous = bones connected by dense regular connective tissue
  • Cartilaginous = bones joined by cartilage
  • Synovial = articulating bones separated by a fluid-filled cavity, instead of cartilage
• Fibrous joints

  Suture: synarthrosis, fibrous

  Syndesmosis: amphiarthrosis, fibrous

  Gomohosis: synarthrosis, fibrous

  Synchondrosis: synarthrosis, hyaline cartilage

  symphysis: amphiarthrosis, fibrocartilage
• What do synovial joints do?

  allows for greater movement and reduce friction
