The term "immovable joint" refers to a joint in the body that does not allow for movement. However, in contrast, there are joints in the body that do allow for movement. These joints are known as movable joints, and examples include the hip, knee, elbow, and shoulder joints. Movable joints allow for a wide range of motions, such as bending, twisting, and rotating. In contrast, immovable joints, also known as fibrous joints, provide support and stability to the body. While immovable joints are essential for keeping the body in place, movable joints enable humans to perform various physical activities and undertake a wide range of movements.
