Flat bones are bones that are thin, flat, and often curved. They are composed of two thin layers of compact bone with a layer of spongy bone in between.

Here are some examples of flat bones in the human body:

Skull:

* Frontal bone: Forms the forehead.

* Parietal bones (2): Form the sides and roof of the skull.

* Occipital bone: Forms the back of the skull.

* Temporal bones (2): Form the sides of the skull below the parietal bones.

* Sphenoid bone: Forms the base of the skull.

* Ethmoid bone: Forms part of the roof of the nasal cavity.

Other:

* Scapula (shoulder blade):

* Sternum (breastbone):

* Ribs:

* Ilium (pelvis):

Functions of Flat Bones:

* Protection: They protect vital organs, such as the brain, heart, and lungs.

* Muscle attachment: They provide a large surface area for muscle attachment, allowing for movement.

* Blood cell production: The spongy bone within flat bones contains red bone marrow, which is responsible for producing blood cells.

It's important to note that some bones, like the ribs, are classified as flat bones even though they have a slight curve to them.
