Which bone is the shoulder blade?

• A. Lacrimal Bone
• B. Zygoma
• C. Scapula
• D. Olecranon

Answer: (C)

The shoulder blade is the scapula. It is a large, flat, triangular bone located on the back of the rib cage, forming the posterior part of the shoulder girdle. The scapula has landmarks like the spine running across its surface, the acromion that extends to form the outer shoulder, and the coracoid process on the anterior side. It connects with the humerus at the glenoid cavity to create the shoulder joint and with the clavicle at the acromioclavicular joint, allowing a wide range of shoulder movements. The other bones mentioned serve different regions: the lacrimal bone is a small eye socket bone, the zygoma (zygomatic bone) is the cheekbone, and the olecranon is the tip of the elbow on the ulna.
