Solution

Ball and socket joint is between humerus and scapula.

Hinge joint is between the humerus of the upper arm and the ulna and radius of the forearm.

Pivot joint : Pivot joints allow for rotation, which can be external (for example when rotating an arm outward), or internal (as in rotating an arm inward).Example is proximal and distal radioulnar joint

Condyloid joint : Oval shaped condyle of one bone fits into elliptical cavity of other bone. These joints allow biaxial movements i.e. forward-backward and side to side but not rotation. Example is the wrist joint.

Saddle joint : The carpometacarpal joint of the thumb makes the human thumb opposable by allowing it to move across the palm to contact the other four fingers of the hand.

Plane joint :Plane joints permit sliding movements in the plane of articular surfaces
