Which joint is essentially immovable

Smooth cartilage prevents friction as the bones move against one another. In freely movable joints, the entire joint is enclosed inside a membrane filled with lubricating synovial fluid, which helps to provide extra cushioning against impact. Muscles are attached to bones with thick, tough bands of connective tissue called tendons.

Where tendons lie close to bone, tiny sacs called bursae sit between the tendon and the bone to reduce friction. A bursa is filled with synovial fluid.

Key Takeaways Key Points The type and characteristics of a given joint determine the degree and type of movement. Structural classification categorizes joints based on the type of tissue involved in their formations. Of the three types of fibrous joints, syndesmoses are the most movable. Cartilaginous joints allow more movement than fibrous joints but less than synovial joints. Synovial joints diarthroses are the most movable joints of the body and contain synovial fluid.
