Shoulder joint

thingiverse

Structures that comprise the human shoulder joint play a crucial role in facilitating an extensive range of motions, including flexion, extension, abduction, adduction, rotation, and circumduction. The shoulder joint itself is a complex ball-and-socket joint formed by the articulation of the humerus bone with the scapula. A vital component of this joint is the glenoid cavity, a shallow depression in the scapula that serves as the recipient site for the head of the humerus. The articulating surfaces of both bones are covered with cartilage, allowing for smooth movement and minimizing friction during motion.
