The breakdown typically includes the 26 bones of the vertebrae (24 movable vertebrae, the sacrum, and the coccyx), the sphenoid and ethmoid bones of the skull, and the mandible. For instance, fractures of the mandible or sphenoid bone require specialized knowledge due to the proximity of major nerves and blood vessels.

This brings the total count of irregular bones to **six**. Moving down the spine, the sacrum and coccyx are also classified as irregular bones; they are formed from the fusion of multiple smaller vertebrae and form the posterior wall of the pelvic cavity.
Specific vertebrae, such as the atlas (C1) and axis (C2) in the neck, are highly irregular, allowing for the complex rotational movement of the head. Bones like the sphenoid and ethmoid are intricately shaped, containing air sinuses and forming parts of the eye sockets and nasal cavities.
