Sternum

manubriumbreastbonesternal
These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
The sternum or breastbone is a long flat bone located in the central part of the chest.

Skull

craniumcranialhuman skull
These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage.
The skull is made up of a number of fused flat bones, and contains many foramina, fossae, processes, and several cavities or sinuses.

Occipital bone

The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
Like the other cranial bones, it is classed as a flat bone.

Hip bone

The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
The hip bone (os coxae, innominate bone, pelvic bone or coxal bone) is a large irregular bone, constricted in the center and expanded above and below.

Scapula

The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
In humans, it is a flat bone, roughly triangular in shape, placed on a posterolateral aspect of the thoracic cage.

Rib cage

These bones are expanded into broad, flat plates, as in the cranium (skull), the ilium (pelvis), sternum and the rib cage. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, hip bone (coxal bone), sternum, ribs, and scapulae.
The sternum is a long, flat bone that forms the front of the rib cage.

Long bone

long boneslong
Since flat bones are usually thinner than the long bones, they only have red bone marrow, rather than both red and yellow bone marrow (yellow bone marrow being made up of mostly fat).
They are one of five types of bones: long, short, flat, irregular and sesamoid.

Ossification

Ossification is started by the formation of layers of undifferentiated connective tissue that hold the area where the flat bone is to come.
Intramembranous ossification forms the flat bones of the skull, clavicle and mandible.

Neurocranium

In the cranial bones, the layers of compact tissue are familiarly known as the tables of the skull; the outer one is thick and tough; the inner is thin, dense, and brittle, and hence is termed the vitreous (glass-like) table.

Red blood cell

In an adult, most red blood cells are formed in flat bones.

Diploë

The intervening cancellous tissue is called the diploë, and this, in the nasal region of the skull, becomes absorbed so as to leave spaces filled with air–the paranasal sinuses between the two tables.
