The term "ball-and-socket" refers to a specific type of joint which has a rounded end that fits into a socket on another bone, allowing for a wide range of motion. It is commonly associated with the hip and shoulder joints. However, there are several other synonyms that can be used to describe this joint type, such as "spheroid," "enarthrosis," or "articulatio spheroidea." Other medical terms that describe the ball-and-socket joint include "multiaxial joint" and "triaxial joint," which refers to their ability to move in multiple directions. Regardless of the term used, the ball-and-socket joint is an essential component of the human body, allowing for fluid movement and flexibility.
