In tloing so they carry the per- itoneum before them, producing introversion of the simple sac, and forming folds which connect them with the wall or with each other. The viscera thus receive a complete or partial covering of peritoneum, termed the visceral layer (Lamina visceralis). The connecting folds are termed omenta, mesenteries, ligaments, etc. Tliey I'ontain a varying cjuantity of connective tissue, fat, and lymph glands, and furnish a path for the vessels and nerves of the viscera. Some contain unstriped muscular tissue. An omentum is a fold which passes from the stomach to other viscera. There are three of these, namely: (1) The lesser omentum (Omentum minus),' which passes from the lesser curvature of the stomach to the liver; (2) tlu> gastro-splenic omentmn (Ligamentum gastrolienale), which ex- tends from the greater curvature of the stomacl to the spleen; (3) the greater omentum (Omen tum majus),- which passes from the greater curva- ture of the stomach and from the spleen to the terminal part of the great colon and the origin of the small colon. It does not pass directly from one organ to the other, but forms an extensive loose sac (ligs. 377, 378). A mesentery (]\Iesen- terium) is a fold which attaches the intestine t<i the
