Anatomical terminology

The trabecular arteries are the name of the branches of the splenic artery after it passes into the trabeculae of the spleen, where it branches. When these arteries then reach the white pulp, and become covered with periarteriolar lymphoid sheaths, the name changes again to central arteries (or central arterioles). Branches of the central arteries are given to the red pulp, and these are called penicillar arteries).
