    Three types of joints found in the human body are:

    1. Hinge Joint: A hinge joint allows movement in only one plane, similar to the opening and closing of a door. It enables flexion and extension movements. An example of a hinge joint is the elbow joint, which allows the bending and straightening of the forearm.

    2. Ball-and-Socket Joint: A ball-and-socket joint allows movement in multiple directions, including flexion, extension, abduction, adduction, and rotation. It consists of a rounded end of one bone fitting into a cup-like socket of another bone. The hip joint is an example of a ball-and-socket joint, where the rounded head of the femur fits into the socket of the pelvic bone, allowing for a wide range of movement.

    3. Pivot Joint: A pivot joint allows rotational movement around a central axis. It enables the rotation of one bone around another bone. An example of a pivot joint is the atlantoaxial joint between the first and second vertebrae of the neck, which allows for the rotation of the head.

    These different types of joints provide the body with flexibility and mobility, allowing for various movements and activities.
