What is the common name for the clavicle?

The clavicle is commonly known as the collarbone. This name is derived from the bone's position and shape, resembling a collar or a support structure for the shoulders and neck. The clavicle connects the arm to the body and plays a crucial role in stabilizing the shoulder, facilitating arm movement.

Unlike the other choices, the term "shoulder blade" refers to the scapula, which is a different bone located at the back of the shoulder. The "upper arm bone" pertains to the humerus, which is the bone of the upper arm, while the "wrist bone" refers to any of the bones in the wrist area, known collectively as carpals. Each term defines a distinct part of the skeletal system, highlighting that the clavicle's common nomenclature specifically identifies it as the collarbone.
