Comparative histological studies of Jejunum in cattle, sheep and goat

Abstract

Jejunum in cattle, sheep and goat comprised four types of layers tunica mucosa, tunica submucosa, tunica muscularis and tunica serosa. Tunica mucosa was innermost layer, which comprised lamina propria with number of glands. Intestinal glands were lined by number of goblet cells tall columnar cells and enterochromaffin cells. Lamina muscularis was with circular and longitudinal layers of smooth muscle fibre. Tunica muscularis was comprised of circular and longitudinal muscle fiber. Outrmost layer was tunica serosa which was a loose connective tissue with blood vessels.
