Bone Anatomy Hematopoiesis. In birds and mammals bone marrow is the primary site of new blood cell production or haematopoiesis. Blood cell formation also called hematopoiesis or hemopoiesis continuous process by which the cellular constituents of blood are replenished as needed.
While a complete blood count provides information regarding possible treatment-related effects reflected in the peripheral blood morphological evaluation of bone marrow cytology and paraffin sections provides information about bone marrow tissue architecture that otherwise would be missed by examin. The red blood cells erythrocytes the white blood cells leukocytes and the blood platelets thrombocytes. However this function of bone marrow becomes restricted to the axial skeleton by adolescence.
With age it is largely replaced by yellow marrow for fat storage.

The non-vascular sections of the bone marrow are where hematopoiesis or blood cell formation. This section will examine the gross anatomy of bone first and then move on to its histology. Numerous sites of hematopoiesis exist at birth.
