The outer muscles on the front of the neck insert on which bone?

• A. Humerus
• B. Scapula
• C. Clavicle
• D. Cervical Vertebrae

Answer: (C)

The muscles on the outer front of the neck, especially the sternocleidomastoid, have an attachment that includes the clavicle. One part of this muscle originates from the clavicle (and the other part from the sternum), with the muscle running upward toward the head. Because the clavicle serves as a primary anchor point for these neck muscles, it’s the bone most closely associated with their insertion/origin compared with the other options. The humerus and scapula belong to the shoulder/arm region, and the cervical vertebrae are the neck bones themselves, but the superficial front neck muscles anchor to the clavicle rather than these other bones.
