Only back and forth movement is allowed by
Hinge joint
A hinge joint is a common class of synovial joints that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. Pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely movable joint that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament. An example of a pivot joint is the joint of the first and second vertebrae of the neck that allows the head to move back and forth.The bones cannot move at fixed joints. The bones in our skull are a perfect example of this kind of joints.The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. Example are the shoulder and hip joints.
