Identify the classification of bones that includes the vertebrae and maxilla.

The classification of bones that includes the vertebrae and maxilla is categorized as irregular bones. Irregular bones are characterized by their unique shapes and do not fit into the other standard categories of flat, long, or sesamoid bones.

The vertebrae, which form the spine, have a complex structure that allows for flexibility and protection of the spinal cord. Similarly, the maxilla, which is a major bone of the facial skeleton, has an intricate shape that contributes to the structure of the face and the cavity for the upper teeth. These bones are categorized as irregular because they perform specific functions that require their unique shapes, unlike the more uniform shapes of flat bones (like the skull), long bones (like the femur), or sesamoid bones (like the patella).

Thus, classifying both the vertebrae and maxilla as irregular bones reflects their complex structures and specialized roles in the skeletal system.
