The skull and ribs are considered to be what kind of bones?

The skull and ribs are classified as flat bones, which is supported by their structure and function. Flat bones are characterized by their thin, flattened shape and typically serve protective roles as well as areas for muscle attachment.

In the case of the skull, it encases and protects the brain, while also providing structure to the face. The ribs protect vital organs in the thoracic cavity, such as the heart and lungs, and together with the sternum, they form a protective enclosure. These bones have a broad surface area, which allows for extensive muscle attachment, further underscoring their classification as flat bones.

This understanding of bone classification is crucial in anatomy and physiology as it helps in recognizing the various functions bones perform in the body, such as protection, support, and movement facilitation.
