Correct Answer(s) B. Hinge C. Immovable E. Pivot F. Ball and Socket
Explanation The correct answer is Hinge, Immovable, Pivot, Ball and Socket. These are the different types of joints found in our body. A hinge joint allows movement in only one direction, like the movement of a door on its hinges. An immovable joint, also known as a fixed joint, does not allow any movement, such as the joints between the bones of the skull. A pivot joint allows rotational movement, like the movement of the head on the neck. A ball and socket joint allows for a wide range of movement in all directions, like the movement of the hip and shoulder joints.
