normoblast

[′nȯr·mə‚blast]
(histology)
The smallest of the nucleated precursors of the erythrocyte; slightly larger than a mature adult erythrocyte. Also known as acidophilic erythroblast; arthochromatic erythroblast; eosinophilic erythroblast; karyocyte; metakaryocyte; metanitricyte; metarubricyte.

Normoblast

 

one of the stages in the maturation of erythrocytes in the bone marrow of mammals and man. The cytoplasm of a developing normoblast gradually becomes enriched with hemoglobin and the nucleus degenerates, resulting in the emergence of a mature erythrocyte.
