Detailed explanation-1: -Synovial joints are freely movable and allow for motion at the location where bones meet. They provide a wide range of motion and flexibility. Other joints provide more stability and less flexibility. Bones at cartilaginous joints connected by cartilage and are slightly movable.

Detailed explanation-2: -The six types of freely movable joint include ball and socket, saddle, hinge, condyloid, pivot and gliding.

Detailed explanation-3: -Joints allow our bodies to move in many ways. Some joints open and close like a hinge (such as knees and elbows), whereas others allow for more complicated movement-a shoulder or hip joint, for example, allows for backward, forward, sideways, and rotating movement. Immovable, or fibrous, joints don’t move.

Detailed explanation-4: -Synovial joints are capable of the greatest movement of the three structural joint types; however, the more mobile a joint, the weaker the joint. Knees, elbows, and shoulders are examples of synovial joints.
