The clavicle, commonly known as the collarbone, is classified as a long bone. However, it has some unique characteristics that can make it seem a bit different from typical long bones like the femur or humerus.
One reason the clavicle is considered a long bone is its elongated shape, which is longer than it is wide. It serves a vital role in connecting the arm to the body, acting as a strut between the sternum and the shoulder blade. This positioning allows for a wide range of motion in the shoulder.
Despite its classification as a long bone, the clavicle is somewhat flat in appearance, especially compared to more cylindrical long bones. The bone’s structure is unique as it consists of both compact and spongy bone tissue, providing strength and flexibility, which is essential given its function in supporting upper body movements.
