A reticulum is a natural structure that resembles a net or web, like the veins in a leaf or the network of fibers in a cell.

You can use reticulum for anything in nature with a structure that looks like a net. In fact, the Latin meaning of the word is "a little net." Reticulum has been adopted for many scientific uses, including the name of a net-like constellation. A cow or other ruminant's second (of four) stomachs is also called a reticulum, from the honeycomb shape of its lining.
