Surface Structure of Ruminal Papillae of Goat

摘要

A scanning electron microscopic study was conducted on ruminal papillae of six adult goats. The study revealed that the entire ruminal mucosal surface was expanded by numerous papilla of varied shapes and sizes. These papilla varied from short tonguelike to large flattened foliate structures. They were heavily grooved over the entire surface giving an eroded appearance to the ruminal mucosa. These grooves were more pronounced on one side of papilla than on other side. The ruminal surface was covered with horny cells with clear cut boundaries which showed granular appearance of cells due to presence of cytoplasmic protrusions. At higher magnification these protrusions were more flaps like in form and having a contracted arrangement.
