The ribs are an example of which type of bone?

Ribs are classified as flat bones, which are characterized by their thin, flattened shape. This structure provides a broad surface area for muscle attachment and also helps protect vital organs, specifically the heart and lungs, located within the thoracic cavity. Flat bones, including the ribs, skull, and sternum, play a crucial role in forming protective barriers as well as serving as points of attachment for muscles.

In contrast, other types of bones have distinct characteristics: long bones, like the femur and humerus, are longer than they are wide and are primarily involved in movement and support. Short bones, such as those found in the wrist (carpals) and ankle (tarsals), are roughly cube-shaped and provide stability and support while allowing for some movement. Irregular bones, which include vertebrae and certain facial bones, have complex shapes that do not fit into the other categories and serve various functions. Thus, understanding the specific classification of ribs as flat bones helps clarify their anatomical and functional significance in the body.
