Analyze the shape of each bone option

Using the Bone Identification and Bone Classification knowledge points, we evaluate the anatomical shape of each listed bone:

• Sternum: A flat, elongated, T-shaped bone located in the center of the chest.
• Humerus: A long, cylindrical bone of the upper arm.
• Clavicle: An S-shaped, slender long bone (collarbone).
• Scapula: A flat, triangular-shaped bone located on the posterolateral aspect of the thoracic cage (shoulder blade).

Identify the triangular-shaped bone

The scapula is anatomically characterized by its distinct three borders (superior, medial, and lateral) and three angles (superior, inferior, and lateral), which form a clear triangular shape.
