Answer:
Ball and socket joint.
Explanation:
In simple words a synovial joint is a type of joint which articulates two bones and also allows movement. Six types of synovial joints occur in our body at different locations. Ball and socket joint is one of that six types of joints. It is the joint which allows maximum movement of the joining bones because this joint is formed when one bone has a spherical end like a ball and the other bone covers this ball with a cup like structure called socket. Due to such arrangements of bones the joining bones can be moved in any direction and also they can be rotated to some extent.
