    Study Notes

    Types of Joints

    • Fibrous Joint: Bones united by dense regular fibrous connective tissue
    • Cartilaginous Joint: Bones united by cartilage
    • Synovial Joint: Fluid-filled joint cavity separating cartilage-covered articulating surfaces of bones, enclosed within a capsule and united by ligaments

    Functional Classification of Joints

    • Based on the extent of movement allowed at a joint
    • Three types of joints:
      • Fibrous Joints: Immoveable
      • Cartilaginous Joints: Slightly movable
      • Synovial Joints: Freely movable

    Fibrous Joints

    • Three types: Gomphoses, Sutures, and Syndesmoses
    • Bones united by dense regular fibrous connective tissue
    • No joint cavity present
    • Majority are immovable, but some allow movement depending on fiber length

    Joint or Articulation

    • Site where two or more bones meet
    • Unites bones with each other, bones with cartilage, cartilage with cartilage, and bones with teeth
    • Provides mobility and resists forces such as compression, tension, and shear stress
    • Supportive structures align bones and protect from dislocation

    Structural Classification of Joints

    • Based on type of connective tissue binding articulating surfaces and presence of space between surfaces
    • Three types: Fibrous Joints, Cartilaginous Joints, and Synovial Joints
    • Structure determines function
