Explanation:
Detailed explanation-1: -Functionally the three types of joints are synarthrosis (immovable), amphiarthrosis (slightly moveable), and diarthrosis (freely moveable).
Detailed explanation-2: -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.
