Which bone serves as a connection to the shoulder blade?

The clavicle, commonly known as the collarbone, plays a crucial role in connecting the shoulder blade (scapula) to the sternum (breastbone) at the front of the body. This connection is important for stabilizing the shoulder and allowing for a range of motion when the arm is elevated or rotated. The clavicle acts as a strut that helps keep the shoulder joint in place, enabling effective movement during various physical activities.

The scapula, while central to the shoulder complex, primarily serves as the attachment point for muscles rather than a direct connection bone. The sternum is part of the ribcage and does not connect directly to the shoulder blade. The humerus is the upper arm bone that fits into the shoulder socket but does not connect to the shoulder blade itself. Thus, the clavicle is the correct answer as it serves as the essential link in the skeletal framework for movement and stability of the shoulder.
