The most common example of immovable joints are found in the sutures of the adult skull.
The teeth in their sockets form immovable joints as well.
The growth plates of children's long bones are immovable joints.
The joint between the first rib and the breastbone is also an immovable joint.
they are found in a part of the body that can move freely
Synovial joints are those in which the articulating bones are separated by a fluid containing joint cavity.
Joint cavity
The synovial membrane is the inner membrane of tissue that lines a joint. The synovial membrane secretes synovial fluid which serves to lubricate the joint and reduce the friction between bones in joints.
Joints may be synovial (with a cavity) or fibrous. Synovial joints are filled with synovial fluid. Fibrous joints lack this. Fibrous joints are found in between the vertebrae. Cartilage in is both joints. This can be hylaine or fibrocartilage. Both regenerate. The synovial fluid is rather slippery and allows easy movement in those joints. If this joint is suddenly and rapidly pulled, the fluid doesn't fill quickly and a "snapping" sound is heard.

A synovial membrane is most likely to be found in the joint cavity.
Synovial Membranes
Synovial fluid is the fluid found in synovial joints, and is secreted by the synovial membrane. The shoulder, elbow, wrist, hip, knee and ankle are synovial joints, as are metacarpo- and metatarsophalangeal and interphalangeal joints.

synovial joints
Synovial fluid is a thick, stringy fluid found in the cavities of synovial joints. With its egg-like consistency (synovial comes from Latin for "egg"), synovial fluid reduces friction between the articular cartilage and other tissues in joints to lubricate and cushion them during movement.
