What is a ball and socket joint?

 A ball and socket joint is a type of joint in which the rounded end (ball) of one bone fits into the hollow space (socket) of another bone. This arrangement allows movement in all directions, including rotation. It is one of the most flexible types of joints in the human body. A common example is the joint between the thigh bone (femur) and the hip bone. Another example is the shoulder joint. These joints enable us to perform activities like walking, running, and moving our arms freely.
