Collarbone

Collarbone

• A. Coccyx
• B. Coloboma
• C. Cardiovascular
• D. Clavicle

Answer: (D)

The collarbone is the clavicle. It’s the slender, horizontal bone that sits at the base of the neck, extending from the sternum to the scapula and forming the front part of the shoulder girdle. It acts like a support strut, helping keep the shoulder away from the chest so the arm can move freely and the upper limb can transmit forces to the axial skeleton. The other terms refer to different structures: coccyx is the tailbone at the base of the spine; coloboma is a congenital eye defect; cardiovascular relates to the heart and blood vessels.
