Anatomy Exam Notes: Joints and Bone Landmarks

Joint Classification by Structure

  • Cartilaginous Joints:

    • Examples mentioned include Symphysis and Synchondrosis.

    • These are types of joints where bones are united by cartilage.

  • Fibrous Joints:

    • Example mentioned is Suture (found in the skull).

    • These joints are immovable or slightly movable and are united by fibrous tissue.

  • Synovial Joints:

    • Characterized by a joint cavity containing synovial fluid, allowing for greater movement.

    • Examples:

      • Glenohumeral Joint (Shoulder Joint) - Connecting the glenoid fossa of the scapula and the head of the humerus.

      • Humeroulnar Joint (Elbow Joint) - Articulation between the humerus and the ulna.

      • Radioulnar Joint - The articulation between the radius and ulna.

        • Specifically mentioned as a pivot joint, allowing for rotation (pronation and supination).

  • Head: The rounded upper end, articulating with the scapula.

  • Neck: The narrowed region below the head (anatomical neck) and a more distal one (surgical neck, though not explicitly named,
