Anastomosis

 

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.

In this path, the lateral costal branch establishes anastomosis with the posterior and anterior intercostal arteries of the first to eighth intercostal spaces through two fine branches, generating an intermediate longitudinal vascular axis for these arteries, as well as emitting direct branches for the thoracic wall, forming part of the arterial circuit of this wall.
5) In this case, as in other reports of intracavernous anastomosis, (23,6-8) the intracavernous vessel continues as the middle cerebral artery (MCA), while the A1 segment of the anterior cerebral artery (ACA) ipsilateral to the absent ICA is aplastic or hypoplastic; this is slightly different than Lie's original description in which the intracavernous anastomosis supplies both the MCA and ACA territories.
