The mammalian yolk sac placenta.

13 Sep 2009 There are three fetal membranes in mammals, namely the yolk sac, allantois and amnion, but only the first two form a placenta. In Monotremata (monotremes), Marsupialia (marsupials) and Placentalia (eutherians), the yolk sac transfers nutrients ... Read more...

The colonic groove or furrow: a comparative morphological study of six species of African mole-rats (Rodentia, Bathyergidae).

30 Jul 2009 Herbivorous mammals such as nutrias, guinea pigs, chinchillas, and mole-rats have a longitudinal mucosal colonic groove (furrow) in their ascending colon, which is thought to play a role in the colonic separation mechanism (CSM). It is not known ... Read more...

From physiology to classification: comparative anatomy and Vicq d'Azyr's plan of reform for life sciences and medicine (1774-1794).

30 May 2009 Here I analyze the anatomical thought of the French physician and naturalist Félix Vicq d'Azyr (1748-1794) in order to bring to light its importance in the development of comparative anatomy at the end of the eighteenth century. I argue that his ... Read more...
