Fig. 1. Red blood cells and their precursors. 1 and 2, haemocytoblasts ; 3, 4 and 5, early, intermediate and late primary erythroblasts; 6 and 7, basophil and erthochromatic normoblasts; 8, normocyte; 9, 10, l1 and 12, early, intermediate, late and pyknotic megaloblasts; 13, megalocyte ; 14, 15, 16 and 17 early, intermediate, late and pyknotic primitive megaloblasts; 18, primitive erythrocyte; 4a, basophil normoblast with prematurely pyknotic nucleus; 10a, megaloblast with prematurely pyknotic nueleus. Jenner.

Fig. 2. 125 mm foetus. Focus of megalo-normoblaetic erythropoiesis in neck. One early and several intermediate megaloblasts forming pyknotic megaloblasts and - with loss of nucleus - a Inegalpcyte, and — from shrinkage in size — orthochrematic normoblasts and — by loss of nucleus - a normocyte. Jenner.

Historic Disclaimer - information about historic embryology pages

Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?
