Answer
Freely movable joints allow flexibility, slightly movable joints provide strength with limited flexibility, and immovable joints provide a strong base of support with secure enclosures and offer maximum joint protection.
Work Step by Step
Freely movable, slightly movable, and immovable joints cannot be placed anywhere in our body. For example, if our shoulder was replaced with an immovable joint our shoulder would have no use in that we would not be able to rotate it or move it in any way. So the location of our joints and their types have an anatomical reason.
