The Ultra Structural Studies of Duodenum of Goat (Capra hircus)

ABSTRACT

The tissues from small intestine containing duodenum were collected from six young goats and processed for scanning and transmission electron microscopic studies. The villi of the duodenum varied in shape and size. The duodenal mucosal surface showed leaf shaped villi along with scanty population of goblet cells on the villi surface. The mucosal surface was having very faint corrugations and dense mat of microvilli. The basal surface of the villi, the number of goblet cells was more. The crypts openings were evident at some places. The transmission electron microscopic studies revealed the presence of different cell population which included columnar or absorptive cells and goblet cells in surface epithelium of the duodenum. The columnar cells were having many uniform regularly spaced microvilli. The goblet cells were very few in the villus epithelium and were interspersed in between the columnar cells and their cytoplasm was distended with mucus granules. The crypt region or glandular epithelium was consisted of polymorphic cell population which included the Paneth cells, enterochromaffin cells and goblet cells
