What type of bone is the scapula?

The scapula, commonly known as the shoulder blade, is classified as a flat bone. This classification is based on its structure and function. Flat bones are typically thin, flattened, and often slightly curved, providing a surface for muscle attachment and protection for underlying organs.

In the case of the scapula, its broad and flat shape allows it to serve as an attachment point for several muscles involved in shoulder and arm movement, such as the deltoid and rotator cuff muscles. Additionally, the scapula plays a key role in the overall stability of the shoulder girdle and facilitates the range of motion necessary for upper limb activities.

While long bones, irregular bones, and short bones serve different functions and have distinct anatomical features, they do not fit the description of the scapula as effectively as flat bones do. Thus, the classification of the scapula as a flat bone underscores its role in providing both structural support and muscle attachment in the shoulder region.
