What type of bone are the ribs considered to be?

Ribs are classified as flat bones due to their structure and function. Flat bones are typically thin and provide protection to internal organs, as well as serve as a base for muscle attachment. The ribs fulfill these roles by encasing the thoracic cavity, protecting vital organs such as the heart and lungs, and providing support for the muscles of the back and chest. Their flat, curved shape contributes to their ability to shield these organs effectively, differentiating them from other types of bone that serve different purposes, such as long bones, which are more elongated and primarily involved in movement and support, or irregular bones, which have complex shapes and fulfill various roles in the body. Thus, the classification as flat bones is based on both their anatomical characteristics and their functional significance.
