Sternum is a flat bone present just under beneath the skin in the middle of the front of the chest.

Glenoid Cavity is the depression which articulates with the head of the humerus to form the ball and socket joint in pectoral girdle.

Freely Movable Joints are characterised by the presence of a fluid filled synovial cavity between the articulating surface of the two bones. This fluids represents the synovial fluid, e.g., in gliding and hinge joints.

Cartilagenous Joints are present between the adjacent vertebrae in the vertebral column.
