Which type of joint permits multiaxial movement, such as shoulder rotation?

Movement about multiple axes and planes is the hallmark of a ball-and-socket joint. Its rounded head sits in a cup-like socket, allowing the limb to move in many directions: flexion and extension, abduction and adduction, internal and external rotation, and circumduction. This is why the shoulder can rotate and reach in so many positions—the glenohumeral joint provides multiaxial freedom. In contrast, hinge joints mainly bend and straighten in one plane (uniaxial), pivot joints rotate around a single axis, and gliding joints allow sliding movements with limited directions.
