Which of the following bones is classified as long bone?

The clavicle is classified as a long bone because it has an elongated shape and consists primarily of a shaft with two ends. Long bones are typically characterized by their longer length than width and are crucial for supporting the body and facilitating movement. The clavicle, or collarbone, plays an important role in connecting the arm to the body and provides structural support.

In contrast, the patella is classified as a sesamoid bone since it is embedded within a tendon and protects that tendon. The phalanges, while long, are categorized as short bones due to their smaller size compared to the overall structure of long bones. The scapula, also known as the shoulder blade, is a flat bone, which has a different shape and function than long bones. Each type of bone serves distinct purposes and is categorized based on specific structural characteristics.
