Flat bones do not have diaphysis or epiphyses. These bones are composed of
two thin layers of cortical bone sandwiching trabecular bone tissue, which is the
location of red bone marrow. In an adult, most red blood cells are formed in flat
bones. These bones have generally a dimension much smaller than the other two.
Examples are the cranial bones, sternum or the scapula.
Like the flat bones, irregular bones do not possess diaphysis or epiphyses and
are assembled by two thin layers of cortical bone enclosing trabecular bone tissue.
In these bones there is no preferential dimension or shape. Irregular bones serve
