Histogenesis of Intestinal Tomentum of the Mongolia Sheep′s Embryo

Using the normal method of histology,the histogenesis of embryonic intestines of 32~550 mm about the Mongolia sheep is investigated.The result shows that the histogenesis of intestinal tomentum in all stems exists during the process of development and the histogenesis of intestines presents diverse characteristics.The histogenetic time,generated course and the degenerated time of intestinal tomentum are quite difference from each other.
