    Study Notes

    Synovial Joint Classification

    • Synovial joints categorized by range of movement and shape of articulating bones.

    Ball and Socket Joints

    • Feature a ball-shaped head of one bone that fits into a cup-shaped socket of another.
    • Allow extensive movement: flexion, extension, adduction, abduction, rotation, and circumduction.
    • Examples include the shoulder and hip joints.

    Hinge Joints

    • Structurally resemble door hinges, permitting mainly flexion and extension.
    • The elbow is a prime example, allowing forearm movement in these two directions.
    • Other hinge joints include the knee, ankle, and interphalangeal joints (between fingers and toes).

    Gliding Joints

    • Comprise flat or slightly curved surfaces, enabling limited gliding movements.
    • Represent the least movable type of synovial joints.
    • Examples include joints between carpal bones in the wrist, tarsal bones in the foot, and spinal vertebrae processes.

    Pivot Joints

    • Allow rotational movement of a bone or limb.
    • One bone fits into a ring-like structure formed by a ligament, facilitating rotation.
    • Notable example is the joint forming between the dens of the axis and the atlas ligament.

    Condyloid Joints

    • Characterized by a rounded condyle that sits in a cup-shaped depression of another bone.
    • Enable movements such as flexion, extension, abduction, adduction, and circumduction.
    • Examples include the joint between the mandible's condylar process and the temporal bone, as well as joints in the hand and foot.

    Saddle Joints

    • Bones interlock similar to a person sitting in a saddle.
    • Most significant saddle joint is at the base of the thumb, between the trapezium and the first metacarpal bone.
    • Movement range parallels that of condyloid joints but offers added flexibility, including thumb opposition, which allows touching all fingertips on the same hand.
