Joints form the location where our bones connect with one another. They are formed of tough connective tissue that facilitate a specific range of movements of our limbs. Depending on whether the joint is synovial, fibrous, or cartilaginous, it can either allow for anywhere between a great degree of movement, or none at all. The connective tissue found in joints can be classified as one of two main types: ligaments and tendons. Ligaments are the connective tissue that connect bones to other bones, while tendons connect muscles to bones.

Key Points

  • Joints
    • Locations where bones connect (or articulate)
    • Connections to bone at joints
      • Ligaments connect bones to bones
      • Tendons connect muscle to bone
    • Types of Joints
      • Synovial 
        • Allows for movement 
        • Ex: shoulder, knee 
      • Fibrous 
        • Tightly held bones with minimal movement 
        • Ex: teeth, skull bones 
      • Cartilaginous
        • Tightly held bones connected by cartilage
        • Ex: ribs, sternum, pelvis
