In the latter sense, there are two types of erythroblasts: normoblasts as cells that develop as expected, and megaloblasts as unusually large erythroblasts that are associated with illness. There are four stages in the normal development of a normoblast.

Normoblast. Reticulocyte. Erythrocyte (fully mature red blood cell). Your bone marrow releases mature blood cells into your bloodstream. Once they’re in your bloodstream, your red blood cells can move oxygen from your lungs to your tissue. They can move carbon dioxide from your tissues to your lungs (to be exhaled).

A normoblast is the originator that extrudes a nucleus to form a reticulocyte. You might find these chapters and articles relevant to this topic. RBCs are formally called erythrocytes. Nucleated RBC precursors, normally restricted to the bone marrow, are called erythroblasts.

Normoblast, nucleated normal cell occurring in red marrow as a stage or stages in the development of the red blood cell (erythrocyte). Some authorities call the normoblast a late-stage erythroblast, the immediate precursor of the red blood cell; others distinguish the …

A nucleated red blood cell, the immediate precursor of a normal erythrocyte in humans. Its four stages of development are: 1) pronormoblast, 2) basophilic normoblast, 3) polychromatic normoblast, and 4) orthochromatic normoblast. See also: erythroblast

The meaning of NORMOBLAST is an immature red blood cell containing hemoglobin and a pyknotic nucleus and normally present in bone marrow but appearing in the blood in many anemias.

It is the immediate precursor of a normal erythrocyte. The term normoblast is sometimes used as a synonym for erythroblast, but at other times it is considered a subcategory. In the latter context, there are two types of erythroblasts: There are four stages in the development of a normoblast.
