in animals, connections between nerves, muscles, and blood or lymphatic vessels. Anastomoses between arteries and veins, without the formation of capillary networks—that is, arteriovenous anastomoses—are of importance in regulating the blood supply of organs. In clinical practice, anastomosis is the name given to a connection between tubular organs which is artificial or has arisen as a consequence of disease. In higher plants, anastomosis is the connecting of tubular structures—for example, veins in leaves and branchings of latex vessels. In fungi, anastomosis is the connecting or concresence of two mycelium hyphae with the establishing of intercommunication between them. This occurs with an insufficiency of food and plays a role in the formation of diploid mycelium and the heterokaryon of haploid mycelium, since the cell nuclei move from one cell into another through the anastomoses.
