  • In <em>anatomy</em>, an interlacing of nerves, vessels, or fibers; a net-like arrangement of parts, or the parts so disposed: especially said of certain delicate vascular membranes chiefly composed of minute anastomosing blood-vessels, as the choroid plexus, and of similar arrangements of nerves of the spinal and sympathetic systems.
  • In <em>mathematics</em>, a system of one-fold relations.
